Franck Mortelmans came from a talented artistic family: he was the cousin of the Antwerp still-life painter Frans Mortelmans (1865-1936), the sculptor August Mortelmans and the composer Lodewijk Mortelmans. Franck was born in Antwerp and undertook his artistic training at l’Académie d’Anvers under the instruction of Frans Hens and Isidore Opsomer. His early exhibited works were town scenes with an Impressionist feel but it was not long before he moved on from this style and started working in a more harmoniously blended manner utilising large coloured surfaces. His commissioned portraits were evenly distributed between society and middle class sitters and were very much in the 19th century tradition. In 1930 he started to produce a lot more landscapes and these were notable for having vast atmospheric skies. He worked in pastels as well as oils and was also a draughtsman and illustrator and as well as the portraits, for which he is best remembered, and the landscapes mentioned previously, he also painted a number of very sensitively observed still-lifes. In 1924, Mortelmans became Professor of l’École Professionnelle des Meniers d’Art d’Anvers and held the same post at l’Académie de Berchem in 1936. In 1958, he became Director of the latter and was also Director of l’Académie d’Anvers between 1946 and 1963. In the later stages of his life, Mortelmans dedicated an increasing amount of his time attempting to halt the advance of 20th century development as it encroached on the landscapes and important monuments of the country. Many of these held a particular resonance for him because he had accurately recorded them on canvas and paper in his travels around Antwerp and its environs. His work can be seen in the museums of Antwerp and Ostend.
