Richard Charles "Dick" Lewontin (born March 29, 1929) is an American evolutionary biologist, mathematician, geneticist, and social commentator. A leader in developing the mathematical basis of population genetics and evolutionary theory, he pioneered the application of techniques from molecular biology, such as gel electrophoresis, to questions of genetic variation and evolution. In a pair of seminal 1966 papers co-authored with J.L. Hubby in the journal Genetics, Lewontin helped set the stage for the modern field of molecular evolution. In 1979 he and Stephen Jay Gould introduced the term "spandrel" into evolutionary theory.
Lewontin has worked in both theoretical and experimental population genetics. A hallmark of his work has been an interest in new technology. He was the first person to do a computer simulation of the behavior of a single gene locus (previous simulation work having been of models with multiple loci). In 1960 he and Ken-Ichi Kojima were the first population geneticists to give the equations for change of haplotype frequencies with interacting natural selection at two loci. This set off a wave of theoretical work on two-locus selection in the 1960s and 1970s. Their paper gave a theoretical derivation of the equilibria expected, and also investigated the dynamics of the model by computer iteration. Lewontin later introduced the D' measure of linkage disequilibrium. (He also introduced the term "linkage disequilibrium", about which many population geneticists have been unenthusiastic.)  In 1966, he and Jack Hubby published a paper that revolutionized population genetics. They used protein gel electrophoresis to survey dozens of loci in the fruit fly Drosophila pseudoobscura, and reported that a large fraction of the loci were polymorphic, and that at the average locus there was about a 15% chance that the individual was heterozygous. (Harry Harris reported similar results for humans at about the same time.) Previous work with gel electrophoresis had been reports of variation in single loci and did not give any sense of how common variation was.  Lewontin and Hubby's paper also discussed the possible explanation of the high levels of variability by either balancing selection or neutral mutation. Although they did not commit themselves to advocating neutrality, this was the first clear statement of the neutral theory for levels of variability within species. Lewontin and Hubby's paper had great impact--the discovery of high levels of molecular variability gave population geneticists ample material to work on, and gave them access to variation at single loci. The possible theoretical explanations of this rampant polymorphism became the focus of most population genetics work thereafter. Martin Kreitman was later to do a pioneering survey of population-level variability in DNA sequences while a Ph.D. student in Lewontin's lab.

did he find anything in his studies?

He was the first person to do a computer simulation of the behavior of a single gene locus (previous simulation work having been of models with multiple loci).

Erik Weisz was born in Budapest to a Jewish family. His parents were Rabbi Mayer Samuel Weisz (1829-1892) and Cecilia Steiner (1841-1913). Houdini was one of seven children: Herman M. (1863-1885) who was Houdini's half-brother, by Rabbi Weisz's first marriage; Nathan J. (1870-1927); Gottfried William (1872-1925); Theodore (1876-1945); Leopold D. (1879-1962); and Carrie Gladys (1882-1959), who was left almost blind after a childhood accident. Weisz arrived in the United States on July 3, 1878, on the SS Fresia with his mother (who was pregnant) and his four brothers.
Houdini performed at least three variations on a buried alive stunt during his career. The first was near Santa Ana, California in 1915, and it almost cost Houdini his life. Houdini was buried, without a casket, in a pit of earth six feet deep. He became exhausted and panicked while trying to dig his way to the surface and called for help. When his hand finally broke the surface, he fell unconscious and had to be pulled from the grave by his assistants. Houdini wrote in his diary that the escape was "very dangerous" and that "the weight of the earth is killing."  Houdini's second variation on buried alive was an endurance test designed to expose mystical Egyptian performer Rahman Bey, who had claimed to use supernatural powers to remain in a sealed casket for an hour. Houdini bettered Bey on August 5, 1926, by remaining in a sealed casket, or coffin, submerged in the swimming pool of New York's Hotel Shelton for one and a half hours. Houdini claimed he did not use any trickery or supernatural powers to accomplish this feat, just controlled breathing. He repeated the feat at the YMCA in Worcester, Massachusetts on September 28, 1926, this time remaining sealed for one hour and eleven minutes.  Houdini's final buried alive was an elaborate stage escape that featured in his full evening show. Houdini would escape after being strapped in a straitjacket, sealed in a casket, and then buried in a large tank filled with sand. While posters advertising the escape exist (playing off the Bey challenge by boasting "Egyptian Fakirs Outdone!"), it is unclear whether Houdini ever performed buried alive on stage. The stunt was to be the feature escape of his 1927 season, but Houdini died on October 31, 1926. The bronze casket Houdini created for buried alive was used to transport Houdini's body from Detroit to New York following his death on Halloween.

Where else did he perform this stunt?
submerged in the swimming pool of New York's Hotel Shelton
