Editing Thomas Hunt Morgan (section)

==Personal life==
On June 4, 1904, Morgan married [[Lillian Vaughn Morgan|Lillian Vaughan Sampson]] (1870–1952), who had entered graduate school in biology at Bryn Mawr the same year Morgan joined the faculty; she put aside her scientific work for 16 years of their marriage when they had four children. Later she contributed significantly to Morgan's ''Drosophila'' work. One of their four children (one boy and three girls) was [[Isabel Morgan]] (1911–1996) (Marr. Mountain), who became a [[virologist]] at Johns Hopkins, specializing in [[poliomyelitis|polio]] research. Morgan was an atheist.<ref>{{cite book|title=Strange Angel: The Otherworldly Life of Rocket Scientist John Whiteside Parsons|year=2006|publisher=Houghton Mifflin Harcourt|isbn=9780156031790|author=George Pendle|page=69|quote=The Nobel Prize-winning geneticist and stringent atheist Thomas Hunt Morgan was developing the chromosome theory of heredity by examining his swarm of mutated Drosophila (fruit flies) through a jeweler's loupe.}}</ref><ref>"Morgan's passion for experimentation was symptomatic of his general skepticism and his distaste for speculation. He believed only what could be proven. He was said to be an atheist, and I have always believed that he was. Everything I knew about him—his skepticism, his honesty—was consistent with disbelief in the supernatural." Norman H. Horowitz, [http://www.genetics.org/content/149/4/1629.short T. H.
