was born in Turku, Finland, in 1930. He studied in the Art Academy of
Finland from 1950 to 1954. He then spent two years studying in the art
academies of Perugia and Venice and travelling in the Middle East. Returning
to Finland in 1959 he found the material - wood - which he has been working with ever since.
Hartman is known for his big architectural log constructions, which can be
best understood in the light of the Scandinavian wooden building tradition.
He takes old logs from demolished houses, builds rather than carves, using
the chainsaw and the axe. The biggest of his wooden sculptures, 18.5 metres
high, is in Volvo headquarters, Gothenburg Sweden.
also uses wood and other materials in his smaller sculptures, which he
himself considers just as important as the big ones. During all his career,
Hartman has also painted a lot, and during the past few years painting has
become increasingly important to him.
