Ferdinand "Nand" Peeters (Mechelen, October 13, 1918 – Turnhout, December 27, 1998) was a Belgian obstetrician and gynecologist, whose research led directly to the development of Anovlar, the first combined oral contraceptive pill introduced outside the United States, in 1961, the first whose side-effects were acceptable, and the first that was used world-wide (Albach 1997:939). It remained in production, in its original formula, from its introduction until 1986 — although, beginning in 1964, Schering AG (the company that produced it) also marketed variants with lower doses of hormones, some of which continued to be named Anovlar. Nand Peeters's research also contributed substantially to the treatment of Rh-disease.
