Margaret Crane: the artist who invented the home pregnancy test

other · 2026-05-13

In 1967, at the age of 26, New York artist Margaret Crane created a prototype for a pregnancy test while employed by Organon. Drawing inspiration from a paperclip holder, her invention utilized urine to identify hCG, resulting in a dark ring if the hormone was detected. Despite doubts from Organon executives concerned about potential backlash, Crane continued her efforts. In 1969, a patent was filed in her name, but she relinquished her rights for just one dollar. Alongside Ira Sturtevant, she established Ponzi & Weill, introducing "The Predictor" in Montreal in 1971, which gained U.S. approval in 1977. Crane's achievements went largely unnoticed until 2012, and in 2015, she sold the original prototype for over $11,000. Now at 85, her prototype resides in the Smithsonian.
