Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman who has been described as America's greatest inventorHe developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures.
Otto Hahn (8 March 1879 – 28 July 1968)[1] was a German chemist and pioneer in the fields of radioactivity and radiochemistry. In 1938, Otto Hahn and Lise Meitner discovered nuclear fission (but only he received the Nobel Prize for the discovery). He is referred to as the father of nuclear chemistry.He was awarded the Nobel Prize in Chemistry in 1944 for the discovery and the radiochemical proof of nuclear fission.This process is exploited by nuclear reactors and is one of the basics of nuclear weapons that were developed in the U.S, Britain, and Canada, during World War II.
Charles Darwin
Charles Robert Darwin, ;12 February 1809 – 19 April 1882) was an English naturalist, geologist and biologist,best known for his contributions to the science of evolution.His proposition that all species of life have descended over time from common ancestors is now widely accepted, and considered a foundational concept in science.In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.Darwin has been described as one of the most influential figures in human history,and he was honoured by burial in Westminster Abbey.
Albert Einstein
Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicistwho developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).
Louis Pasteur (December 27, 1822 – September 28, 1895) was a French biologist, microbiologist and chemist renowned for his discoveries of the principles of vaccination, microbial fermentation and pasteurization. He is remembered for his remarkable breakthroughs in the causes and prevention of diseases, and his discoveries have saved many lives ever since. He reduced mortality from puerperal fever, and created the first vaccines for rabies and anthrax.
