Frans Alfons Janssens Frans Alfons Janssens (Sint-Niklaas 23 July 1865 - Wichelen, 8 October 1924). Ordained as a priest in 1886, he obtained a PhD in Natural Science with the highest honors and a scholarship to attend the most prestigious foreign laboratories. He worked with Professor Kjeldahl at the Hansen Institute Carlsberg Brewery in Copenhagen and was a teacher at the St. Lawrence Brewery School in Ghent. In 1896, he became a professor at the Faculty of Sciences for the Catholic University of Leuven, as a chair in microscopy and later in cytology, succeeding Jean-Baptiste Carnoy in the chair. He is the discoverer of the crossing-over of genes during meiosis, which he called 'chiasmatypie'. His work was continued by the Nobel Prize winner Thomas Hunt Morgan to develop the theory of genetic linkage.
