L. was born on 13 December 1887 in Petrikov, Minsk Gubernia, White Russia, into a well-to-do family. He learned Tenach and Gemora in a cheder, also Russian and Hebrew. At age nine he already was writing songs in Hebrew. At age twelve he founded a journal in Hebrew.

In 1905 he went to America, and here he debuted with songs in the "Fraye arbeter shtime", and in the "Forward" and with stories in Pinski's "Idisher arbeter" and Dr. Vartsman's "Idishe shtime". Later he became a collaborator in Joseph Tunkel's humorous page "Der kibitzer", of which he took over in 1909 the editing for six years. During the break, when the "Kibitzer" didn't used to publish, L. collaborated in the "Kunds".

Under the pseudonym Regidebel and the [lebediker], L. had earlier in a humorous journal, afterwards in "Di varhayt", "Tog" and over he last years in the "Morning Journal", published hundreds of humorous feuilletons about Yiddish literature and Yiddish theatre. In his eight volumes of scripts, that were in 1928 published by Warsaw's publisher "Akhisfr", included two volumes "di ferte vand" [211 pp., 16°], and "Shpil un lebn" [206 pp., 16°], exclusively humorous articles, critiques, reviews and feuilletons about Yiddish theatre and Yiddish actors.

L. also wrote humorously in dialogue form and several of them were acted or were performed in small arts evenings and concerts.
