Wolf Bickel (born 6 July 1942, Bensberg) is a German amateur astronomer and a prolific discoverer of asteroids, observing at his private Bergisch Gladbach Observatory, Germany. He is the most successful German discoverer of minor planets.^[2][3]

Bickel studied electrical engineering at RWTH Aachen University and finished his studies in 1969. He became enthusiastic about astronomy, when he received a celestial chart and Galilean binoculars as a gift from his grandmother at the age of 16. Bickel began to grind parabolic mirrors to build his own telescopes. In 1995, he built a 0.6-meter aperture telescope and discovered his first minor planet, the main-belt asteroid (14053) 1995 YS₂₅ the same year. He still uses this self-made telescope as of today.^[2]

He lives in Bergisch Gladbach, in the Cologne–Bonn Region of North Rhine-Westphalia, Germany. The Minor Planet Center confused Bickel's home town with the location of his observatory, which is located 30 kilometers from his place of residence.^[2] Bickel named 12564 Ikeller – an asteroid of the Koronis family, and his one and only named discovery – after his wife, Ingeborg Bickel–Keller (b. 1941).^[4]

The 12-kilometer sized asteroid 4324 Bickel, discovered by American astronomer Laurence Taff in 1981, was named in his honor.^[3]
