Biography.
Hajós was born February 21, 1912, in Budapest; his great-grandfather, Adam Clark, was the famous Scottish engineer who built the Chain Bridge in Budapest. He earned a teaching degree from the University of Budapest in 1935. He then took a position at the Technical University of Budapest, where he stayed
large cliques as minors in a graph. A variant of the Hadwiger conjecture, stated by György Hajós, is that every "n"-chromatic graph contains a subdivision of "K"; if this were true, the Albertson conjecture would follow, because the crossing number of the whole graph is at least as large as the crossing number of any of its subdivisions. However, counterexamples to the Hajós conjecture are now known, so this connection does not provide an avenue for proof of the Albertson conjecture.
