Professor Stephen William Hawking, was born on 8th January 1942 (exactly 300 years after the death of Galileo) in Oxford, England. His father, a well-known researcher in tropical medicine, urged his son to seek a career in medicine, but Stephen found biology and medicine were not exact enough. Therefore, he turned to the study of mathematics and physics. Hawking was not an outstanding student at St. Alban’s School, nor later at Oxford University, which he entered in 1959. He was a social young man who did little schoolwork because he was able to grasp the essentials of a mathematics or physics problem quickly. The onset of Hawking’s graduate education at Cambridge marked a turning point in his life. It was then that he embarked upon the formal study of cosmology, which focused his study. And it was then that he was first stricken with Lou Gehrig’s disease, a weakening disease of the nervous and muscular system that eventually led to his total confinement in a wheelchair. At Cambridge his talents were recognized, and he was encouraged to carry on his studies despite his growing physical disabilities. His marriage in 1965 was an important step in his emotional life. Marriage gave him, he recalled, the determination to live and make professional progress in the world of science. Hawking received his doctorate degree in 1966. He then began his lifelong research and teaching association with Cambridge University. Hawking made his first major contribution to science with his idea of singularity, a work that grew out of his collaboration. A singularity is a place in either space or time at which some quantity becomes infinite. Such a place is found in a black hole, the final stage of a collapsed star, where the gravitational field has infinite strength. Drawing upon the work of both Penrose and Albert Einstein, Hawking demonstrated that our universe had its origins in a singularity. In the beginning all of the matter in the universe was concentrated in a single point, making a very small but tremendously dense body.
