Frans Gieles (b. Circa 1941, PhD in social, clinical and forensic orthopedagogy), is secretary of Ipce and its current curator of online libraries. He has been active in various pedophilia self-help groups since around 1980.
Up until 2010, Gieles hosted and supported Ipce's real-life meetings, and assisted in the running of a private webforum until it was voluntarily closed due to lack of interest. Even at his advanced age, Gieles frequently publishes papers on the subject of relationships between older and younger people.
In 2017, Gieles made an appearance in his local news media after he got trapped in an elevator at his local railway station in Deventer. He was released by engineers soon after.
