Appendix I-B: A Brief Källén Chronology

Abstract

Anders Olof Gunnar Källén was born on 13 February in the city of Kristianstad in the south of Sweden. His academic path is summarized here below:

The above chronology does not include Källén’s numerous shorter trips, for research, giving talks at conferences and lecturing at various schools. He was a highly esteemed visitor in many places and had a standing invitation to several universities and research centers, such as University of New York at Stony Brook, MIT, IHÉS in Paris, and the Theory Center in Marseille. See Chap. 17.

On the private front, on 13 October 1951, Källén married Gunnel Bojs. They had four children: Anders Olof Erland (b. 1954), Anna Karin Kristina (b. 1955), Anna Hilda Elisabeth (b. 1956) and Anders Erik Arne (b. 1958). Gunnel Källén died a few months after her husband, on 6 April 1969.

Källén used to say (jokingly) that 13 was his lucky number – perhaps just to counterbalance the superstitious people who are afraid of number 13. There must quite a number of such people as, for example, in the Scandinavian commercial planes there is no row numbered 13.
