Remembering Lee Lorch

      Lee Lorch was a mathematician known for his social activism on behalf of black Americans as well as for his mathematics. He died in February of this year in Toronto, at age 98.  A life-long communist and a life-long crusader.  Last Thursday I attended a memorial service  (organized by Joe Auslander, a poetry-lover who one day had introduced me to the work of Frank Dux) for Lorch -- sponsored by the Mathematical Association for America and held at the MAA Carriage House in Washington, DC.  Friends and colleagues of Lorch spoke of his positive energy and the ways that he had enriched the lives of students and colleagues, of friends and strangers.  One of the speakers, Linda Braddy, a staff member of the Mathematical Association of America (MAA), did not talk about Lorch but about strategies for opening mathematical doors (as he had done) to new students.
