A personal history of diversity

Just came across the BMES Inaugural Diversity Lecture by Sheldon Weinbaum, in which he gives a broad and personal history of efforts to promote diversity. I've always been impressed by the originality of his scientific ideas, and the passion with which he pursues, presents and defends them. So it should have come as no surprise -- but did anyway -- that he has been on the front lines of the culture wars for nearly half a century(!).
