Franklin P. Mall (1862 - 1917) is most remembered for his work done at the Department of Embryology at the Carnegie Institute of Washington. Mall began collecting human embryos while a postgraduate student in Lepzig with Wilhelm His, but didn't receive the first Carnegie specimen until his position at Johns Hopkins University.

Surprizingly age and size proves a poor way to organize embryos. It is very difficult to accurately age an embryo, and it could shrink a full 50% in the preserving fluids. Mall took it upon himself to find a better way. He had more success basing his "staging" scheme on morphological characteristics.
