Theophilus Shickel Painter (* August 22, 1889; † October 5, 1969 ) was an American Insektenzytologe, which was known by the identification of the genes and is popular with geneticists fruit fly.

His work on the Human Genome and its spermatogenesis have been for some time ( 1921-1956 ) the basis of the firm belief, the human genome possess 48 chromosomes. Although Painter himself initially fluctuated 45-48 in the number of chromosomes, he lay down later to 48 in what became a permanent fixture until proven correct number of 46 by Albert Levan.

Painter received his doctorate in 1913 at Yale University and then worked for a year at Theodor Boveri at the University of Würzburg. In 1916 he accepted a position at the University of Texas at Austin, where he remained until his death. From 1946 to 1952 he was president of the University of Texas.

He discovered in this period (1933 ), for example, that it is an unusual structures in the nuclei of the salivary glands of all (Diptera ) to polytene chromosomes, which consist of several closely paired homologous chromosomes.
