J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels. Dutch journalist Johannes Lambertus Maria ("Hans") Friedeman (1937-1996) enthusiastically reported on space travel, science and the environment. In 1977 he started his own weekly page, and in 1981 this led to the first complete section on science and society in a Dutch newspaper.
