Taiichi Ohno Biography

Taiichi Ohno was a Japanese industrial engineer, recognized as one of the leaders in industrial engineering and designing the Toyota production system and just in time (JIT), within the production system of the automobile manufacturer. he was born on February 29, 1912, in Dalian, China.

in 1932, he graduated from the mechanical technology department of the Nagoya Technical Institute. later, he joined the Toyota textile and yarn weaving plant until its closure in 1942. that same year, he was transferred to Toyota motors as the head manager of the machine shop.

around 1947, under the command of the manufacturing workshop number 2 in the Koromo plant, made some changes to the layout of that area, which introduced machines in parallel lines in the form of an “l” and established the multi-specialization of the operators. two years later, 25662 trucks and 1008 cars were manufactured, and in 1950, with the beginning of the Korean war, the united states recycled part of its trucks and sent some new ones to Toyota.

let the flow manage the process, not the managers administer the flow” Taiichi Ohno.

at the end of 1959, Taiichi Ohno directed the manufacturing and assembly department, where he began to use the Kanban system, which aimed to control the workflow in a manufacturing system through the movement of materials and manufacturing by demand. that same year, when the new Toyota plant was finished in Motomachi, he was named the director for that plant, which facilitated the implementation of the Kanban in the machine shop, press shop, and assembly line.

in 1962, Taiichi Ohno was hired as the general manager of Toyota’s main plant, which allowed him to extend the implementation of the Kanban to the smelting and forging processes.

Taiichi Ohno is known for the creation of the just-in-time production system (JIT). he believed that Toyota’s goal was to cut more time than a customer placed an order until the money was collected by the company. based on this approach, his objective was to reduce the time of activities that do not add value to production.

the projection of Taiichi Ohno covered two fundamental principles: the production at the precise moment and the self-activation of the production, the other aspects were a matter of techniques and procedures of instauration.

Thanks to the contributions of Taiichi Ohno, Sakichi Toyoda, and Kiichiro Toyoda, the Toyota production system (TPS) was created, which is an integrated system of production and management that included the concepts Jidoka (automation), poka-yoke (mistake-proofing), JIT (just in time), Kanban (card), Heijunka (leveling), Andon (manufacturing), Jidoka (intelligent automation), Muda (elimination of waste) and kaizen (continuous improvement).

“my biggest contribution was to build a production system that could respond without waste to market changes and, additionally, by its very nature reduce costs” Taiichi Ohno.

in 1975, Taiichi Ohno was named as the vice-president of Toyota, position in which he was until 1978 when he retired from professional activity.

After a time he held a position on the board of directors of the company until May 28, 1990, the date on which he died.

Willem Einthoven Biography

Willem Einthoven (May 21, 1860 – September 28, 1927) Physiologist and physician. Nobel Prize in Medicine in 1924. He was born in Semarang, Indonesia. He is well known for his contributions to the development of the electrocardiograph and its clinical application. His father died when they lived in Java, so Willem moved to the University of Utrecht to study medicine.

After finishing his studies he obtained the position of professor at the University of Leiden to deal with the positions of physiology and histology. He took the opportunity to advance an important work in the field of research. He quickly showed himself as a reputable scientist, participated in numerous international scientific forums and the best thing is that by managing several languages ​​he could communicate his ideas faithfully without the need for translators.

For several years he experimented with the rope galvanometer and its utility for the registration of cardiac potentials, and the results obtained were published in an article in the year 1901. Five years later, he masterfully described the clinical applications of the electrocardiogram in Telecardiogramme (1906). After that, he published another article that laid the foundations for the development of this important tool in cardiology analysis. His investigative work was carried out simultaneously with his work as a professor.

Thanks to his work, the galvanometer was used to measure the differences in electrical potential during systolic and diastolic heart contractions and reproduce them graphically. This procedure is known as an electrocardiogram.

Later, he was interested in analyzing how healthy hearts worked and then defining a reference frame, through which attention was paid to the deviations caused by the disease. To sum up, he revolutionized the study, diagnosis, and treatment of cardiac pathologies. In his honor, the lunar crater Einthoven bears his name.

Lucy Wills Biography

Lucy Wills (May 10, 1888 – 1964) hematologist and botany. She was born in Sutton Coldfield, United Kingdom. Her family enjoyed a good social and economic position. Therefore, she was able to study at Cheltenham Ladies ’College, an educational institute that offered high educational standards in teaching. Then, she studied Botany and Geology in 1911 but did not receive a Cambridge graduate degree until 1928, when Cambridge began granting degrees to women.

By that time, Wills had admirably managed to graduate as a doctor at the London Royal Free Hospital School of Medicine for Women. From the beginning, he knew that he would devote her knowledge to research and teaching in the Department of Pathological Chemistry of the same center in London. For the year 1928 Margaret Balfour contacted her. For several years she served as chief of pathology until her retirement in 1947.

After her retirement, she worked in South Africa and Fiji studying the effects of nutrition on health. During the last ten years of her life, she was a member of the local government for Chelsea. She started working on macrocytic anemia of pregnancy that primarily affects pregnant women in the tropics, with inadequate diets, this work was developed in several areas of India.

This woman is owed several contributions, such as discovering a nutritional factor in yeast that prevents and cures this disorder: the Wills factor or folate, the natural form of folic acid. In that sense, in the year 1930, she showed that anemia could be reversed with brewer’s yeast, which contains folate.

As part of a recognition of her work and the advancement of medicine, on May 10, 2019, the 131st anniversary of her birth, the Google search engine commemorated Wills with a Doodle available for North America, parts of South America and Europe, Israel, India, and New Zealand. Her knowledge changed the face of prenatal preventive care for women around the world.

Claude Bernard Biography

Claude Bernard (July 12, 1813 – February 10, 1878) physiologist. He was born in Saint-Julien, France. The top representative of the French physiology of the 19th century. His life was dedicated to studying the nervous regulation of salivary secretion, pancreatic digestion, and glycogenic liver function. He is admired for having discovered vasomotor innervation and creating the concept of internal secretion. His contributions to experimental pharmacology are also salvageable.

Bernard at nineteen entered as a clerk in a pharmacy in Vaise, a suburb of Lyon. He liked literature so he wrote a drama entitled Arthur de Bretagne, he went to Paris; but then he started studying medicine, leaving literature aside. At first, he had the guidance of the physiologist François Magendie, who was a trainer, and soon gave proof of his genius. In 1843 he could already demonstrate the glycogenic function of the liver. He was an assistant to Magendie and professor of physiology at Collège de France. In the year of 1853, he obtained the title of doctor of science with the thesis Investigations about a new function of the liver, considered as a producing organ of sugary matter.

The following year he was a professor of experimental medicine at the Collège de France. Years later, and thanks to the knowledge acquired, he wrote Introduction to the study of experimental medicine (1865) allowed him to be part of the French Academy; this year he was entrusted with the chair of general physiology of the Sorbonne Natural History Museum, and in 1869 he was appointed member of the Imperial Senate of Napoleon III. In 1870 his intellectual vitality was affected by a kidney disease contracted because of the cold and humidity of his laboratory.

This French defended the determinism linked to neo-vitalism. He also studied, in addition to hepatic glycogenesis, the sympathetic nervous system and poisons. Among his works are Leçon sur la physiologie expérimentale appliquée a la médecine (1856), Les propriétés des tissus vivants (1866) and Leçon Sur Les phenomènes de la vie (1878).

In broad strokes, his works advocated naturalistic principles and thus generated a great influence that he exerted on the naturalist movement, mainly in Zola. Bernard establishes the rules of medicine that is true science and method, must have a solid foundation. For hi medicine must be like physics and chemistry, a science that undergoes an experimental method. But experience is not proven simply by the facts, without being guided by a precise conviction; rather, it must be rigorous and complete experimentation. So, the philosophical and theological yoke is excluded, admitting a personal scientific authority.

Thus, Bernard says, the hypotheses will encourage discoveries and experimentation serves as a guide. Émile Zola developed in his thinking of naturalist novelist Bernard’s famous scientific premises; his essay The experimental novel represents the attempt to apply the principles of physiology to a conception of art. Unfortunately, he died on February 10, 1878. He is remembered for being one of the referents of experimental physiology of the nineteenth century, and, at the same time, one of the most illustrious thinkers of the time in Europe. The medicine had many advances in an anomaly that affects the sympathetic nerves of the face, it was called Claude Bernard-Horner syndrome.

Similarly, he contributed to the development of therapeutics, diabetes, indications of bleeding, detoxification by carbon monoxide through mechanical ventilation, the treatment of anemia with iron lactate, the decrease in body temperature through physical means, treatment of alcohol intoxication, morphine applications, the effects of carbon dioxide, intravenous administration of physiological serum, cardiopulmonary resuscitation techniques, among others.

Adolf Von Baeyer Biography

Adolf von Baeyer (October 31, 1835 – August 20, 1917) Chemist and Nobel Prize in Chemistry (1905). He was born in Berlin, Germany. He is recognized for the research he carried out on the structure and artificial synthesis of numerous organic compounds. In short, he discovered phenolphthalein and fluorescein. Baeyer is known primarily for the synthesis of indigo.

His father was a military man named Jakob Baeyer, and creator of the European geodetic measurement system. From an early age, Adolf showed great interest in chemistry. His curiosity and intelligence allowed him to synthesize and isolate for the first time a double copper salt with only twelve years of age. Upon finishing his high school studies he entered the University of Berlin to study physics and mathematics. In 1856 he joined the laboratory of Robert Bunsen in Heidelberg. A year later he published the results of several studies on methyl chloride (CH3Cl). In the year of 1858, he was the first research assistant of August Kekulé. The knowledge of this chemist was very helpful in organic chemistry.

Baeyer began studies on uric acid that led to the synthesis of barbituric acid. Then, he served as a professor at the University of Berlin in 1860. Thanks to his long days in the laboratory he discovered that when a complex molecule was subjected to high temperatures in the presence of zinc dust, it could be fragmented. Two of his disciples: Carl Graebe and Karl Liebermann, unraveled the structure of alizarin, a red dye from the root of the tinctorum used to dye the uniforms of the French army.

After seventeen years of studies and research, he found the synthesis of indigo, an intense blue tincture obtained from the leaves and stems of the Indigofera tinctorum. So, he made a synthesis between 1878 and 1882. They were not used for commercial purposes (although, today this dye is necessary for the textile industry). Thanks to this he received the Davy Medal of the Royal Society of London in 1881.

In 1868 he married Adelheid Bendemann. In 1871 he obtained a place at the University of Strasbourg, which he left two years later to start as Professor at the University of Munich. He enjoyed a modern laboratory. He conducted studies on acetylene and polyacetylene, works with benzene and cyclic terpenes, on the other hand, defined the Theory of Torsion, basically, this allows us to understand why those of five and six carbons are the most stable existing cyclic compounds. His work and scientific career were recognized in 1905 with the Nobel Prize in chemistry for his contribution to organic chemistry through chemical dyes. That same year, he turned seventy birthdays, and several of his articles were published in important scientific journals.

Sergey Brin biography

Sergei Brin (August 21, 1973) computer scientist and creator of the Internet search engine Google. He was born in Moscow, Soviet Union. Sergei Brin was born into a Jewish family that enjoyed a well-off position but due to their religious beliefs, the Russian government prevented them from certain possibilities. His father, Mikhail Brin, was a mathematician, and his mother, Eugenia Brin, worked in the field of science when Sergei was six years old they decided to move to the United States to find better living conditions.

When they arrived, their mother landed a major position in NASA’s Goddard Space Flight Center, and her father obtained a position as professor of Mathematics at the University of Maryland, she also decided to change her name, due to North American anti-communist policies, Michael Brin. He entered to study at the Paint Branch Montessori School. His parents were very attentive in the education of his son, who demonstrated a great ability for mathematics. Throughout his school years, he was a student with excellent grades.

Upon graduation, he enrolled at the University of Maryland to study Mathematics and Computer Science. In the stipulated time, 1993, he received his degree with honors and applied for a grant from the National Science Foundation. He began his postgraduate studies at Stanford University. Simultaneously, he started working at Wolfram Research, the creator of Mathematica. While in the winter of 1998, he began to develop an idea to create a search engine for the internet, the idea was developed with the help of Larry Page. His great motivation was the inefficiency and the multiple errors of the search engines existing at that time.

They held several meetings with brilliant people in this field, and they met Andy Bechtolsheim, an investor from Sun Microsystems. They decided to present their idea, they also made a quick demonstration and they got that, without thinking twice, Bechtolsheim extended a check worth 100,000 dollars to start the project. Although with this amount achieved only the beginning of the project, the young people full of enthusiasm began to get other economic support and various sources of income. As a result, Brin and Page managed to get two of the most relevant US venture capital firms, Kleiner Perkins Caufield & Byers and Sequoia Capital, to agree to finance their idea. They then collected 25 million dollars. The project was still ongoing.

At first, they thought of the word googol to baptize their search engine, a term invented by the mathematician Edward Kasner to name the number 1 followed by 100 zeros. Then they changed their name to Google. We must mention that Yahoo! played an essential role in driving Google. Yahoo! collaborated encouraging the creation of his own search engine, the pair of colleagues began to offer in its popular portal the possibility of searching through that engine. For the year 2003, Google swept daily searches, had about 112 million, compared to Yahoo !, which only supported approximately 42 million.

The reason was that Google was more effective, its presentation was much more attractive, and allowed more fixed searches. Brin and Page decided to add new possibilities to the dozen functions related to their search engine and the continuous experimentation with many others. Something really innovative was that Google allowed the users to easily locate images, newsgroups and searches using the Open Directory thematic directory tool, an international volunteer project that catalogs web pages by hand.

After a few years, thanks to the popularity of Google, colleagues received a Webby, a prize. Google was inserting new services every time, such as the search engine of products on sale in the Google network; the product search within mail order catalogs; a language translator, among other new features. When the new millennium began Google began to think about the modification and restructuring of its building located in the Californian region of Mountain View, more than a hundred employees worked in an unusual environment.

So they adopted as a philosophy: to offer a pleasant place to work and with that to motivate and retain employees. Among the renovations are yoga classes, massages, bars, free ice cream machines, food prepared with organic food by two chefs, a ping-pong table, swimming pool, two pianos, and hockey meetings twice a week. The goal of Google at that time was especially to create better search engines, extract information from unstructured sources and databases of long collections of text and scientific information.

Brin has authored more than a dozen articles in top-level academic journals and has also been a lecturer in various international academic forums, most of them are business and technology, in 2002, Brin was proclaimed “Young Innovator Who Will Create the Future” by Technology magazine Review This publication was edited by the prestigious Massachusetts Institute of Technology (MIT). What this couple achieved, especially at Brin’s initiative, was impressive. At present everyone knows and has used Google.

Although it has been censored by some countries of totalitarian politics like China. According to computer experts, Google is “the saving medicine” for most Internet users. One of its characteristics is the speed and effectiveness. Now, its design is simple and direct, and without incorporating advertising in its pages that generate distraction in the users. We must accept that, Internet users have preferred this search engine to the detriment of other, earlier, more popular ones. Brin has advanced several projects, along with Larry Page, who are looking for ways to solve the problem of global energy and environmental hazards through Google’s philanthropic area called Google.org.
