J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels. Paul Crutzen (b. 1933) was a co-recipient of the 1995 Nobel Prize in chemistry for work in atmospheric chemistry, particularly concerning the formation and decomposition of ozone. The name was suggested by W. A. Fröger.
