In 1912, the astronomer at the Harvard Observatory, Henrietta Swan Leavitt, discovered the magnitude-period relationship in Cepheid stars; a relationship that, even today, is one of the fundamental bases for determining cosmological distances. This discovery was reflected in the paper "Period of 25 variable stars in the Small Magellanic Cloud" signed by the director of the observatory, Edward Pickering. Although Pickering points out that the discovery was made by Leavitt, my question is why Leavitt didn't sign the paper?
