 In the 1890s, while engaged to the Finnish pianist Fanny Flodin (1868–1954), Leclercq helped to organize exhibitions of contemporary art, the most important touring in 1898 in Scandinavia.Then, in March 1901, he succeeded in bringing together the first important Van Gogh-exhibition exclusively based on loans from French collectors or art dealers, in Paris.It was at this retrospective exhibition — hosted by the Bernheim-Jeune Galleries — that Paul Cassirer was introduced to the work of Van Gogh.
