Emma K. Manske, Nettie A. Moore, Lilly J. Philp, and Richard MacGregor.
The Computing Scale Company, one of three companies that will form the Computing - Tabulating - Recording Company (C-T-R) in 1911, hires Richard MacGregor, a Black employee, as well as Lilly J. Philp, Nettie A. Moore and Emma K. Manske. This occurs 10 years before the National Association for the Advancement of Colored People (NAACP) was founded, 36 years after President Lincoln signed the Emancipation Proclamation and 20 years before women won the right to vote. In 1924, these four employees help inaugurate IBM's first Quarter Century Club.
