[9] His best-known pupil was Bruno Schmitz, who, after attending the construction class at Wilhelm Lotz [de]'s art academy in 1874, worked in the master builder's studio for four years.

[12] The master builder Hermann Joseph Havenith (5 March 1841 in London – 10 August 1905 in Birstein), who had a building business in Düsseldorf,[13] had built the new house in 1873 (listed since 1983).

[14] In 1882, the architect Rudolf Custodis mentioned in an appeal to the voters not to vote for the candidate Riffarth because of unnecessary expenditures of the city as follows: "The gentleman is a quite capable government builder; has travelled around Egypt and has received quite beautiful impressions of the conditions there, as the chequered art academy building demonstrates ad oculos to everyone.

At the end of 1891, he, who had been a city councillor since the early 1880s, was appointed to the board of the Kunstgewerbeschule together with the mirror and painting frame manufacturer Conzen and the painter Ernst Bosch [de].

[17] At the time of the founding of the Architekten- und Ingenieurverein Düsseldorf [de], Riffart was deputy chairman in 1893, the director of the school of arts and crafts Hermann Stiller had the chairmanship.
