The agency architektengroep Loerakker Rijnboutt Ruijssenaars Hendriks bv was founded in 1956 by Jan Verster and P.K.A.Pennink (see VERS and PENN). In 1960 Jan Verster continued on his own. He was reinforced in 1965 by Tjeerd Dijkstra and Joost Cannegieter (see DIJ1 and CANN). In 1969, Ben Loerakker succeeded Cannegieter as a partner in the partnership. The partnership with the name architektengroep Verster, Dijkstra, Loerakker was changed in 1975 into a b.v. with the name bv Architektengroep VDL. Dijkstra stepped down from the b.v. in 1979 when he was appointed Chief Government Architect and Verster stepped down from the b.v. in 1981. They were succeeded by Kees Rijnboutt and Hans Ruijssenaars (see RIJN en RUIJ). In 1988, Gert Jan Hendriks joined the group and the name became Architektengroep Loerakker Rijnboutt Ruijssenaars bv (see HEN2). In 199? Dick van Gameren and Bjarne Mastenbroek joined the group.
