Israel Yudelman was a Russian Jew, who (according to his naturalisation certificate in 1909) was the son of Moses and Chaihy.  Israel first appeared in a Sheffield directory in 1889 as tailor and jeweller at West Street.  In 1892, he had married Matilda née Weinberg at Leicester.  In the following year, he was listed as a tailor at Change Alley.  More detail was provided in the Census of 1901:  Israel Yudelman was forty years old and had been born in Russia; Matilda had been born in London.  He was living at Woodstock Road and his occupation was stated as electro-plate and cutlery manufacturer.  The Sheffield directory in 1901 listed him as an electro-plate goods merchant in Westfield Terrace.  By 1909, he was living at working at Gell Street.  Matilda died on 7 October 1915 and was buried at Ecclesfield Jewish Cemetery.  Their daughter, Rebecca (1900-1968), later manufactured (or sold) razors and scissors in Rockingham Street.  

Israel Yudelmann (the name acquired an extra ‘n’) remained in Westfield Terrace until 1925, when the business closed.   His trade mark was a lily and the word ‘SJAMBOK’.   Israel’s later life has been difficult to trace.  He may have died in 1940.  An individual with that name was buried at Rainsough Jewish Cemetery, Prestwich, Bury, near Manchester.
