22 September 1816, Brussels - 5 December 1907, Mainz was a Belgian painter of Dutch landscapes.
Orphan Leickert first learned painting in The Hague under the supervision of landscape painters Bartholomeus van Hove, Wijnand Nuijen, and Andreas Schelfhout among many others. Leickert specialised in winter scenes, sometimes romanticising the sky in pale blues and bright pinks. He painted almost all his works in the Netherlands, from 1841-1848 in The Hague and from 1849-1883 in Amsterdam. In 1856, he became a member of the Royal Academy of Amsterdam. At the age of 71 he moved to Mainz, Germany where he later died in 1907.
