Spirited evolutionist and Stellenbosch revisited on a zoological centenary*

P.V. Tobias

The Department of Zoology at the University of Stellenbosch, of which I’m proud to be an honorary member, has had a long and illustrious history. Here I celebrate the memory of its foundation professor, a man ‘sacredly devoted to the pursuit of science’.
