A.J. van der Steur (1895-1963) and G.H. Kleinhout (1881-1958) Albert Johan van der Steur, from a family of architects, graduated from the Technische Hogeschool in Delft in 1920. After this, he went to work at Karel Muller's architectural office in Hengelo. Gerrit Herman Kleinhout, head of the office at J.H.W. Leliman, then brought Van der Steur in as a designer when he took over Leliman's office in 1921 after his sudden death. At the widow Leliman's request, the name remains "Architectenbureau Leliman," but is changed to "Architectenbureau Kleinhout and Van der Steur" in 1930. After Kleinhout's death, Van der Steur enters into a partnership with W.F. Snieder. When Van der Steur dies in 1963, Snieder associates with H. Duyvendak. With the arrival of a third architect, the firm is called Snieder, Duyvendak and Bakker from 1970 to 1992, after which the firm is taken over by J. Snieder, a son of W.F. Snieder. In the pre-war work of the firm the influence of the Amsterdam School, Dudok and the Delft School can be seen, especially the sober detailing. After the war, the firm mainly used the traditional Delft School style in its designs for reconstruction projects. Van der Steur made a name for himself as restoration architect, for example for the Old and New Church in Amsterdam. With his new wing for the town hall in Haarlem (1937-1940), he managed to connect excellently to the existing building. From 1930 he is attached as aesthetic consultant to the Bridges Bureau of the Department of Public Works to which he gives 'advice on architectural aspects and the integration of large river bridges into the landscape'. One of his projects is the IJssel bridge near Deventer. Van der Steur plays an important role in the architectural world through his administrative work. He is an active member of the Association of Dutch Architects, the BNA, from 1928 and between 1945 and 1953 chairman and then honorary chairman of the Association. In the period 1927-1955 he actively participates in international architectural congresses. From 1956 he is a member of the Commission Regulating the Architect's Profession and from 1960 a member of the Implementing Commission Regulating the Architect's Profession. He also devoted himself for many years both as a teacher and as a member of the board of the Academy of Architecture. He also plays a role in the history of the Netherlands Architecture Institute. He was the first chairman of the Stichting Architectuurmuseum, the SAM, which was founded in 1955 with the aim of eventually creating an architecture museum.
