According to Louis Gilrod, at the age of twelve he came to America. At first he was a prompter in Yiddish theatre, then he became a coupletist and was regarded as having achieved quite a high level, and he was in his time a star of concerts. By himself, he used to write both the lyrics and music for his couplets.

According to Boris Thomashefsky, they used to call him "Der litvak", which means that he would have come from Lithuania.

K. was mentioned in Zeifert's "History of Yiddish Theatre". He had written the songs for "Professor" Horwitz's "Ben hador". Popular were his couplets "Khapt nit un klapt nit", "Shikhelekh, zekelekh", "A shtreykele bey kheykele", and his best song was known as "Dos tsiper-blat".

His last connection with Yiddish theatre was as a prompter in New York's Windsor Theatre.

His wife was a chorus girl in the Yiddish theatre.

In 1901 K. passed away from consumption (tuberculosis) in Colorado.
