Independent work at marine laboratories
Born Lilian Vaughan Sampson, she graduated in biology from Bryn Mawr in 1891 and subsequently studied comparative anatomy in Zurich. She returned to the Marine Biological Laboratory as an independent investigator over several summers, publishing studies of molluscan and frog development and investigating regeneration.

The attached-X discovery
After interrupting research for family responsibilities, Morgan returned to experimental work and moved into fruit-fly genetics. In the early 1920s she found a fly with two attached X chromosomes and analyzed their inheritance. Attached-X stocks both tested chromosome-based explanations and became tools for maintaining X-linked mutations.

Laboratory access and formal recognition
Thomas Hunt Morgan provided laboratory space, but Lilian worked independently with her own fly stocks. After moving to California in 1928, she continued publishing single-author research. Caltech appointed her a research associate in 1946, illustrating the gap between her experimental contributions and formal academic employment.

Children’s science education
In 1913 she helped establish the Woods Hole Summer School Club, which developed into the Children’s School of Science. Her emphasis on outdoor observation, collecting organisms and experiments extended practices of experimental biology into children’s education.
