Caption: German-US geneticist Franz Schrader (1891-1962) and US zoologist Sally Hughes-Schrader (nee Hughes, 1895-1984). Schrader was an eminent cytologist who studied the cellular basis of genetics. Hughes performed the first complete dissection of the cranial nerves of the dogfish and made studies of haploidy, parthenogenesis, hermaphroditism, and the life cycle of insects. They married in 1920.
