Hollander Johannis de Rijke worked at the Public Works Department, the Ministry of Home Affairs, Japan, as an engineer for around 40 years, and rendered remarkable services to the improvement of large rivers and Sabo works during his stay in Japan. He was initially assigned to the position of a 4th ranked engineer because of the lack of his teclmical education at school. However, the Government of Japan promoted him in 1876 with the treatment of equal rank of an official appointed by the Emperor's approval and further to the rank of an official appointed by the Emperor in 1891, J. de Rijke had been supported by George Arnold Escher who graduated from Royal Academy at Delft and had worked in the Bureau of Public Works, Holland (Rijkswaterstraat) as an elite engineer. By this paper, the background of G.A.Escher, his personality and profile on J.de Rijke, Hollander engineer C. J. van Doom, will be presented according to his memoirs.
