Henry Modlin, a local retired podiatrist who practiced in Washington, D.C., became a bar mitzvah in 1944 at Congregation B’nai Israel, then located at 14th and Emerson Streets in Washington. On Nov. 8, at Congregation Har Shalom in Potomac, in the company of family and friends, he will celebrate by reading from the Torah at Shabbat services not only reaching his 83rd birthday, but also the 70th anniversary of his bar mitzvah. No one will be listening more closely than his grown grandsons, Ben Samit and Steven Lewis, since both of them read the same portion at their b’nai mitzvah.
