Hypatia advanced math without heading the great library

Hypatia of Alexandria, born around 370 AD, was a brilliant mathematician and philosopher, though she never formally led the famed Library of Alexandria. Instead, she became a leading scholar in the city's intellectual hub, the Musaeum. As the daughter of a mathematician, Hypatia taught philosophy and math, editing crucial works like her father's commentaries on Ptolemy's Almagest and Euclid's Elements.
