A memorial to, as WFB describes him, "in our time, the original activist," shot dead at age 51 by a former associate. The program-the first such retrospective on Firing Line (others would be done for Clare Boothe Luce, Michael Harrington, Malcolm Muggeridge, and Barry Goldwater)-is composed of excerpts from Mr. Lowenstein's nine Firing Line appearances, framed by the eulogies given at his memorial service by Mr. Buckley and Senator Edward Kennedy. EMK: "He was a person of impassioned political conviction, but personally he loved so many who so often disagreed with his politics. Who but Al Lowenstein could claim among his best friends both Bill Buckley and Robert Kennedy?" WFB: "Of all the partisans I have known, from the furthest steppes of the spectrum, his was the most undistracted concern, not for humanity-though he was conversant with big-think idiom-but for human beings."
