Karl Lotz was born in Bad Homburg vor der Höhe, Germany, the 7th and youngest surviving child of Wilhelm Christian Lotz and Antonia Höfflick. He began his artistic career as a pupil of the Hofkapellmeister Destouches[disambiguation needed], then in the academy of the Venetian master Jakab Marastoni (1804-1860). Later he was a pupil of the historical painters Henrik Weber (1818-1866) in Budapest and Carl Rahl (1812-1865) in Vienna. Together with Rahl he worked on numerous commissions. Later he started on his own original works, first as a romantic landscape artist in scenes of the Alföld (the Hungarian lowland plain), and then as a creator of monumental murals and frescos in the style of the Venetian master Tiepolo. After various works in Budapest he became active in Vienna. He laid out plans for a grandiose palace, and completed murals commissioned by the Abbot of Tihany Abbey for his abbey church on the shore of Lake Balaton. He became known for his portraits and nudes, for which both his wife and his daughters (Katarina in particular) posed. Lotz found married bliss only at the age of 58. In 1882 Lotz was appointed Professor at various art academies in Budapest, and in 1885 he became dean of a newly established department for women painters. He was an honorary member of the Academy of Pictorial Arts in Vienna. Hist last important public commission was the "Apotheosis of the Habsburg Dynasty", a huge ceiling fresco in the Habsburg Room of the newly rebuilt Royal Palace, that he painted in 1903, one year before his death. Lotz was already seriously ill when he worked on the fresco. The "Apotheosis" followed the traditions of Baroque court painting and the work was praised by contemporary critics. The fresco survived the war unscathed, but it was destroyed in the 1950s. He died in 1904 in Budapest. As a "Prince of Hungarian Artists" he was given a state funeral and interred inside a memorial. His pictures, drawings and sketches were donated to the State of Hungary and are now in the Szépművészeti Múzeum. Several Hungarian cities have streets named after him, there are Hungarian stamps bearing his likeness, and there is a bust in the National Museum in Budapest.
