H G Callan died on the 3rd November, 1993, at the age of 76. ‘Mick’, to all who knew him, had continued an active ‎scientific life up to the brief illness which preceded his death. He was one of the last of a line of scholars whose ‎knowledge and interests encompassed the whole scope of biology. However, it is for his major contribution to our ‎understanding of the structure of chromosomes, and how they function in replication and in the expression of their genes, ‎that Mick will be remembered best by the scientific community. In particular, Mick Callan’s name is inseparably linked ‎with the giant lampbrush chromosomes of amphibian oocytes which provided such a powerful model for universal ‎features of chromosome organisation and activity. ‎
