Once or twice a year I get email from fellow Litwacks, which I very much appreciate - being a Litwack is a singular and often solitary thing. The question most frequently asked is “are we related?” I don’t know, but a good place to start is LitwackFamily.com. The best-known Litwacks are Harry (Temple basketball coach), Leon (historian) and Gerald (biochemist, my father) and as far as I know I’m not related to the first two. I’ve heard various things about the name over the years - Russian Jews all seem to know it; the extraction seems to be Russian or Belorussian and not Lithuanian as one might expect. (Belarus was formerly known as ‘Litwa;’ I have no idea if that’s meaningful.) If you’re a Litwack, why not leave a comment or something?
