# Géry van Outryve d'Ydewalle

Géry van Outryve d'Ydewalle (Brugge, 18 December 1946) is a Belgian scientist. He was professor in psychology with memory and cognition as main topics. He was head of the Laboratory of experimental psychology at the Katholieke Universiteit Leuven (Leuven) until 2012. He worked for some time with Professor William Kaye Estes at Rockefeller University (N.Y.) and lectured at the London School of Economics. In 1992, he was awarded the Francqui Prize on Human Sciences and was elected member of the Royal Flemish Academy of Belgium for Science and the Arts. From 1980 till 2004 he was successively member, Deputy Secretary-General (1984), Secretary-General (1992) and President (1996) of the International Union of Psychological Science. He has been elected as permanent secretary of the Royal Flemish Academy in succession to professor Niceas Schamp, as of 1 September 2010. Géry van Outryve d'Ydewalle has been active as a musician (traverso) in several chamber orchestras. He is the fifth of six children of Baron Pierre van Outryve d'Ydewalle, governor of West-Flanders from 1944 to 1979.

His ancestor, Emmanuel-Louis van Outryve d'Ydewalle [nl] (originally van Outryve; 1745-1827) was created a ridder/("knight") 21 September 1771;, a hereditary title in male line. Géry van Outryve d'Ydewalle's father, Pierre, was elevated to the rank of Baron in 1982.
