With profound sadness, the family of Yasushi Takahashi wishes to announce his passing on February 12, 2013 leaving behind his wife, Betty, two sons, Hiroshi and Atsushi, daughter-in-law, Yi-Fen and relatives in Japan and Ireland.
Yasushi was born in Osaka, Japan and spent his childhood in Japan and in Taiwan. He attended university in Japan and studied theoretical physics before coming to North America for post doctoral work. In 1957, he moved to Ireland to work at the Dublin institute for Advanced Studies. He met his wife, Betty and had two sons. In 1968, the family relocated to Edmonton when he was appointed as a professor in the department of Physics at the University of Alberta. His dedication to the research in Quantum Electrodynamics lead to the Ward-Takahashi Identity. He was a Fellow of both the Royal Society of Canada and the American Physical Society, as well as a Member of the Royal Irish Academy. He collaborated with many physicists from all around the world and inspired many students through teaching and the physics textbooks he wrote. In his spare time, Yasushi enjoyed writing short stories, doing carpentry and listening to classical music. He will be remembered as an outstanding physicist, caring teacher, and loving husband, father and friend.
A private ceremony was held and a memorial will take place at a later date.
