(b Eemnes, 11 June 1859; d Zeist, 28 Oct 1922). Dutch architect. He was the son of a Dutch Reformed Minister and studied at Delft Polytechnic, where he was influenced by the Renaissance Revival doctrines of Eugen Gugel. For a long time Posthumus Meyjes himself worked in this style, most notably in his design for the administrative office (1882–4) of the Dutch Iron Railway Company at Droogbak 1A, Amsterdam. In 1882 he became architect to the railway company, in which position he designed the station in Delft, and in 1888 he established himself as an independent architect in Amsterdam, where he was appointed architect of the church buildings of the Dutch Reformed community. In this capacity he built several churches and supervised the restoration over several years of the medieval Nieuwe Kerk on the Dam in Amsterdam. Around 1900 Posthumus Meyjes’s style changed and began to show similarities to the work of H. P. Berlage, for example in the office building (1900) at Herengracht 179, Amsterdam. From 1905–6, however, he resumed his more traditional style, for example in the office building (1918) at Keizersgracht 55, Amsterdam. He was actively involved with architectural associations and worked as editor on the periodical De Opmerker from its foundation in 1883 until 1887. As an expert on restoration, he was also for many years a member of the National Committee for the Conservation of Buildings and was one of the consultants for the restoration of Utrecht Cathedral. His son Christian Bernardus Posthumus Meyjes the younger (b 1893) also worked as an architect.
