I'd never seen a picture of Judah David Eisenstein before.
Sometimes it's nice to reflect on how fleeting time is. This obituary, dated 5.18.1956, is for a man who wrote a letter to Moses Montefiore when he was 30 years old. Montefiore was born in 1784.
Since he died before blogging, Eisenstein sometimes like to write letters to newspapers. Here's one to the New York Times from 1935. It's about Syriac.
