Carl Eric Wickman (born Erik Wretman; August 7, 1887 – February 5, 1954) was a Swedish-born businessman who was the founder of Greyhound Lines.
[1] Wickman was born Erik Wretman at Martisgården, a family farm located near the small village of Limbäck in the parish of Våmhus, 15 km north of Mora in the province Dalarna, Sweden.
He was the son of farmer Karl Viktor Wretman (1858-1947) and Anna Matsdotter (1862-1943) and the maternal grandson of hair jewelry artist Martis Karin Ersdotter.
When he could not sell the first Hupmobile he received, he began operating a livery route from Hibbing and Alice, Minnesota.
[3][4][5] In 1925, he bought a small line operating out of Superior, Wisconsin that was owned by Orville Swan Caesar (1892–1965).
