# Ida Martha Metcalf

August 26, 1857 - October 24, 1952

Ida Metcalf was born in 1857. In the 1870's she taught in
various one-room schools in New Hampshire communities. In 1886 Metcalf
earned her
Baccalaureate degree from Boston University. She then attended Cornell
University, receiving her
M.S. degree in 1889. In 1893 she became the second American woman to receive
a Ph.D. in mathematics with a dissertation entitled
"Geometric Duality in Spaces". For a time she was an assistant to
Professor George Williams Jones in writing his mathematical textbooks,
drill books in algebra and trigonometry, and logarithm and interest
tables. Metcalf worked for a time as a security analyst in a banking
office in New York, then won a competitive examination for a Civil
Service position in the office of the Comptroller of New York City. She
apparently was the first woman to win such an examination. She served
in this office until her retirement. Metcalf was fluent in French and read both Latin and Greek. She tutored mathematics and Latin after hours, even when she was in the comptroller's office
