Her husband, T.H. Morgan, encouraged her but did not collaborate with her. Instead, he gave her working space in his laboratory, called the "Fly Room," at Columbia University, where she maintained her own Drosophila stocks but held no official position.
The passage describes how T.H. Morgan supported his wife's work by providing her a workspace and resources, but he did not actively participate in her research. She was responsible for managing her own Drosophila stock within the "Fly Room" at Columbia University without holding an official position.
