Asteroid 6629, Kurtz, was discovered on October 17, 1982 by Edward "Ted' Bowell at the Anderson Mesa Station of the Lowell Observatory near Flagstaff, Arizona. It has a period of 3 years,79 days and is about 1 3/4 miles in diameter.
It was named for prominent philosopher, secular humanist, and paranormal skeptic Paul Kurtz (1925-2012), who founded the Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP). He was also chairman of the Council for Secular Humanism, and founder and chairman of Prometheus Books and known for being influential in turning philosophy toward activism as opposed to a pure analytical study. Among practitioners of paranormal arts and sciences and believers in psi phenomena, he was notorious for what they saw as willful closed-mindedness.
