Just pick someone, significant, that makes us go Oooh! Google a bit and add to the list...

Nobutoshi Kihara
Engineer at Sony born in 1926 retired in Sep 2006 - is that 80 years at the same company?

So in 1978, CEO founder of Sony walks up to the guy and says I want a gadget to listen to operas on my frequent trans-Pacific plan trips and ta da - the Walkman was born.

He helped develop first commerically successful transistor radio, first magnetic tape recorders, digital cameras. What really miffs him though is that after working on the Betamax, the world was forced to use the 'inferior' VHS.

Maria Montessori

Born in 1870 in Italy, she attended all-boy technical school in her dreams of being an engineer. She ended up us the first female doctor in Italy. A devout catholic, she put her theories into proof while in the care and education of mentally retarded children.

In 1915, she was invited to the USA by Alexander Graham Bell, Thomas Edison, and others. She set up a classroom in San Francisco, where spectators watched twenty-one children, behind a glass wall, for four months.

The only two gold medals awarded for education went to this class, and the education of young children was altered forever.

She had a son with a doctor colleague but was never married.
(August 31, 1870 – May 6, 1952)

Norman Ernest Borlaug

(March 25, 1914 – September 12, 2009)[1] was an American agronomist, humanitarian, and Nobel laureate who has been called "the father of the Green Revolution".[2] Borlaug was one of only six people to have won the Nobel Peace Prize, the Presidential Medal of Freedom and the Congressional Gold Medal.[3] He was also a recipient of the Padma Vibhushan, India's second highest civilian honor.

During the mid-20th century, Borlaug led the introduction of these high-yielding varieties combined with modern agricultural production techniques to Mexico, Pakistan, and India. As a result, Mexico became a net exporter of wheat by 1963. Between 1965 and 1970, wheat yields nearly doubled in Pakistan and India, greatly improving the food security in those nations.[4] These collective increases in yield have been labeled the Green Revolution, and Borlaug is often credited with saving over a billion people worldwide from starvation.[5] He was awarded the Nobel Peace Prize in 1970 in recognition of his contributions to world peace through increasing food supply.

Dedan Kimathi

Dedan Kimathi Waciuri (October 31, 1920 - February 18, 1957) was a Kenyan rebel leader who fought against British colonization in Kenya in the 1950s. He was convicted and executed by the British colonial government. The British colonial government that ruled Kenya at the time considered him a terrorist, but many Kikuyu and other Kenyans viewed him as a freedom fighter of the Mau Mau Uprising.

Early life - Kimathi was born in Thenge Village Tetu division, Nyeri District. At the age of fifteen, he joined the local primary school, Karuna-ini, where he perfected his English skills. He would later use those language skills to write extensively before and during the uprising. He was a Debate Club member in his school. He was deeply religious and carried a Bible regularly. He worked for the forest department collecting tree seeds to help him foot his school bill. He later joined Tumutumu CSM School for his secondary learning, but dropped out for lack of funds.

He dabbled with several jobs but never felt fully settled. Notable was his enlisting with the army to fight in the Second World War in 1941. However, in 1944, he was expelled for misconduct. In 1946, he became a member of the Kenya African Union. In 1949, he started teaching at his old school Tumutumu, but left the job within two years.

Mau Mau movement - Nevertheless, he managed to be very influential to whomever he met through the string of jobs he was able to obtain. He became radically political in 1950. He involved himself with the Mau Mau, and later that year administered the oath of the Mau Mau, making him a marked man. He joined Forty Group, the militant wing of the defunct Kikuyu Central Association in 1951. He was elected as a local branch secretary of KAU in Ol' Kalou and Thomson's Falls area in 1952. He was briefly arrested in that same year, but escaped with the help of local police. This marked the beginning of his violent uprising. He formed Kenya Defence Council to co-ordinate all forest fighters in 1953.

In 1956, he was finally arrested with one of his wives, Wambui. He was sentenced to death by a court presided by Chief Justice Sir Kenneth O'Connor, while he was in a hospital bed at the General Hospital Nyeri. In the early morning of February 18, 1957 he was executed by the colonial government. The hanging took place at the Kamiti Maximum Security Prison

Legacy - Kimathi was buried in a mass grave and to this day the British government objects to his reburial as it felt (and continues to feel) that he was a terrorist. He is, however, viewed by many Kenyans especially from his tribe as a national hero. Many towns in Kenya have a building or street named after him, Including popular t-shirts designed to immortalize his image by brands like Jamhuri wear. The play "Trial of Dedan Kimathi" was written by Ngugi wa Thiong'o (the brother of a Mau Mau member) and provides a detailed account of Kimathi.

A statue of Kimathi is being built on Kimathi Street in Nairobi. Its foundation stone was laid in December 11, 2006 Kimathi was married to Mukami Kimathi. Among their children are sons Wachiuri and Maina and daughters Nyawira and Wanjugu

carl gauss, an incredible mathematician. He came up with the gauss theorem.

Usain Bolt'9.58' biography

Erasto Mpemba - a Tanzanian high-school student to whom the "Mpemba Effect" is credited. The Mpemba effect is the observation that, in certain specific circumstances, warmer water freezes faster than colder water. New Scientist recommends starting the experiment with containers at 35 °C (95 °F) and 5 °C (41 °F) to maximize the effect.[1]

Mpemba first encountered the phenomenon in 1963 in Form 3 of Magamba Secondary School, Tanzania when freezing hot ice cream mix in cookery classes and noticing that they froze before cold mixes. After passing his O-level examinations, he became a student at Mkwawa Secondary (formerly High) School, Iringa, Tanzania. The headmaster invited Dr. Denis G. Osborne from the University College in Dar Es Salaam to give a lecture on physics. After the lecture, Erasto Mpemba asked him the question "If you take two similar containers with equal volumes of water, one at 35 °C (95 °F) and the other at 100 °C (212 °F), and put them into a freezer, the one that started at 100 °C (212 °F) freezes first. Why?" only to be ridiculed by his classmates and teacher. After initial consternation, Dr. Osborne experimented on the issue back at his workplace and confirmed Erasto's finding. They published the results together in 1969..

Dr. Philip Emeagwali, was born in Nigeria in 1954. Like many African schoolchildren, he dropped out of school at age 14 because his father could not continue paying Emeagwali's school fees. However, his father continued teaching him at home, and everyday Emeagwali performed mental exercises such as solving 100 math problems in one hour. His father taught him until Philip "knew more than he did."

The noted black inventor received acclaim based, at least in part, on his study of nature, specifically bees. Emeagwali saw an inherent efficiency in the way bees construct and work with honeycomb and determined computers that emulate this process could be the most efficient and powerful. In 1989, emulating the bees' honeycomb construction, Emeagwali used 65,000 processors to invent the world's fastest computer, which performs computations at 3.1 billion calculations per second.

Dr. Philip Emeagwali's resume is loaded with many other such feats, including ways of making oil fields more productive – which has resulted in the United States saving hundreds of millions of dollars each year. As one of the most famous African-American inventors of the 20th century, Dr. Emeagwali also has won the Gordon Bell Prize – the Nobel Prize for computation. His computers are currently being used to forecast the weather and to predict the likelihood and effects of future global warming.

It's hard to say who invented the Internet. There were many mathematicians and scientists who contributed to its development; computers were sending signals to each other as early as the 1950s. But the Web owes much of its existence to Philip Emeagwali, a math whiz who came up with the formula for allowing a large number of computers to communicate at once.

Emeagwali was born to a poor family in Akure, Nigeria, in 1954. Despite his brain for math, he had to drop out of school because his family, who had become war refugees, could no longer afford to send him. As a young man, he earned a general education certificate from the University of London and later degrees from George Washington University and the University of Maryland, as well as a doctoral fellowship from the University of Michigan.

At Michigan, he participated in the scientific community's debate on how to simulate the detection of oil reservoirs using a supercomputer. Growing up in an oil-rich nation and understanding how oil is drilled, Emeagwali decided to use this problem as the subject of his doctoral dissertation. Borrowing an idea from a science fiction story about predicting the weather, Emeagwali decided that rather than using 8 expensive supercomputers he would employ thousands of microprocessors to do the computation.

The only step left was to find 8 machines and connect them. (Remember, it was the 80s.) Through research, he found a machine called the Connection Machine at the Los Alamos National Laboratory, which had sat unused after scientists had given up on figuring out how to make it simulate nuclear explosions. The machine was designed to run 65,536 interconnected microprocessors. In 1987, he applied for and was given permission to use the machine, and remotely from his Ann Arbor, Michigan, location he set the parameters and ran his program. In addition to correctly computing the amount of oil in the simulated reservoir, the machine was able to perform 3.1 billion calculations per second.

The crux of the discovery was that Emeagwali had programmed each of the microprocessors to talk to six neighboring microprocessors at the same time.

The success of this record-breaking experiment meant that there was now a practical and inexpensive way to use machines like this to speak to each other all over the world. Within a few years, the oil industry had seized upon this idea, then called the Hyperball International Network creating a virtual world wide web of ultrafast digital communication.

The discovery earned him the Institute of Electronics and Electrical Engineers' Gordon Bell Prize in 1989, considered the Nobel Prize of computing, and he was later hailed as one of the fathers of the Internet. Since then, he has won more than 100 prizes for his work and Apple computer has used his microprocessor technology in their Power Mac G4 model. Today he lives in Washington with his wife and son.

"The Internet as we know it today did not cross my mind," Emeagwali told TIME. "I was hypothesizing a planetary-sized supercomputer and, broadly speaking, my focus was on how the present creates the future and how our image of the future inspires the present."
