Hans Gustaf Ivar Morsing was the son of the artist Leopold Morsing (1887-1971) who seems a worthy, and from the evidence of google a rather dull, academic painter. Morsing first studied art at the summer schools held by Swedish designer and artist Edvin Ollers (1888-1959), but at the outbreak of war in 1939, he was conscripted into the Swedish army. As Sweden's neutrality developed he was one of the first students to attended Gösta and Irma Bergh's Technical School of Advertising (which later became Berghs School) between 1940-1941. There he studied decorative arts, design, life drawing, and illustration. This was then followed by a year with the Modernist painter Isaac Grünewald (1889-1946) at the school he founded in 1941 following his departure as professor at the Royal Swedish Academy of Arts. After the war, Morsing first travelled to Denmark followed quickly by two year-long painting trips to France and Italy.

He exhibited widely in Sweden after the war, notably in 1946 and 1952 at Elsa Lindström's 'Modern Konst i Hemmiljö' (Modern art in the home) on Strandvägen in Stockholm. His travels in the early 1950s took him to Italy, France, Tunisia and Paris – taking in Portugal, Spain and Morrocco by motorbike in 1954.

He is represented in the collections of Moderna Museet, Stockholm and museums in Kalmar and Jönköpings.
