Gävle Labyrinth

Yat Malmgren (28 March 1916 – 6 June 2002) was a Swedish dancer and acting teacher. He was born in Gävle, Sweden, as Gert Olof Sigurd Eriksson, to Gustaf Sigurd Eriksson and Signe Emma Maria Malmgren, but changed his surname because of his strained relationship with his father. He used his mother's maiden name, Malmgren, instead. He became known as Yat rather than Gert when he lived in Britain because of difficulties with the Swedish pronunciation of the letter G.
