Vlastimil Dlab

Vlastimil Dlab (born 5 August 1932) is a Czech-born Canadian mathematician who has worked in Czechoslovakia, Sudan, Australia and especially Canada where he founded and led an influential department of modern mathematics.

[1] Dlab was born on August 5, 1932, in Bzí, Czechoslovakia, a historical village whose territory currently belongs to Železný Brod.

So in 1971, he left for Ottawa, Canada where he founded and led a department of modern mathematics at Carleton University that has significantly influenced the world of algebra, probability, and statistics.

Because his father was ill in the early 1980s, Dlab – as an alien – was allowed to visit Czechoslovakia and he restored his relationship with Charles University.

Claus Michael Ringel was the co-author of some of the most famous academic works by Dlab, such as the 1976 book Indecomposable representations of graphs and algebras.
