S. U. Zuidema

Sytse Ulbe Zuidema (22 April 1906 – 28 September 1975) was one of the second generation of reformational philosophers arising from the Free University of Amsterdam, after the first generation of Herman Dooyeweerd and D. H. Th. Vollenhoven. Other members of the second generation included Hendrik Van Riessen, K. J. Popma and J. P. A. Mekkes.

Zuidema was born in Kampen. Prior to teaching philosophy at the Free University, he held a chair of Calvinistic philosophy at the University of Utrecht. He had also been a minister in the Reformed Churches and a missionary in Indonesia. His doctoral dissertation was on William of Ockham. Zuidema died in Amstelveen in 1975.

Robert Knudsen and Hendrik Hart both completed their doctoral dissertations in philosophy under Zuidema.
