If you wish to make a contribution in his memory, please send it to the MGH Division of Nephrology Renal Unit Research Fund, Bigelow 1008, 55 Fruit St., Boston 02114. This fund supports young investigators in the renal division at MGH, who find it hard to get funding for their projects via the regular pipeline. Alan loved teaching the future radiologists at MGH, BU Medical Center, and Tufts New England Medical School, and often drew undecided students into radiology by virtue of his enthusiasm for the field.
