My mother , Adina KATZOFF, writes in her autobiography ("A child of the dessert")
about a William POSNER who lived with my parents in Philly during the mid-1930s.
He was a New Yorker who studied social work at U. of P. and "eventually became
prominent in his field" but they never heard >from him since his graduation.
I would be interested to know what became of him, very good chance he
is not "among us" today as he probably would've been about 105 today.
My mother who is 103 today writes that he became a big brother to her.
