Moses Samuel was born in 1740 (or 1742), initially settled in Liverpool, died in England in 1839. He married Rachel, the daughter of Jonas Phillips, as did his sister Esther marry a child of the same Jonas Phillips.

Together with his brother David, he settled in England. He became a prominent merchant in London during the reign of King George II. He was known as Moses Samuel of Bath and Park Crescent, and also as Moses Legeorge (Hebraized to Logurik).

His children and grandchildren married into the most prominent families of England which included Barent Cohen, DeWorms, Salomons, Rothschild, Jessel and Goldsmid.

• Cecil Roth, in his 'History of the Great Synagogue' (1950, p 194-5) writes:

Moses Samuel Pulvermacher, a leading member of the Great Synagogue, its Warden from 1794 onwards, and its representative of the Board of Deputies; was partly instrumental in the acquisition of the new cemetry on Brady Street, where he lies buried, and built a synagogue for the dimunitive congregation in Bath, where he went to take the waters.
His brother David, who preceded him to England, was also a stalwart worker for the congregation, a Warden in 1784-6 and one of the Vestry when the present Great Synagogue was constructed.

• Hannah Cohen wrote:

Moses was a man of culture and of liberal views; it was at his instigation that English instead of Hebrew was first used for the sermons in the Sabbath morning services, and the custom spread from Liverpool to London, where it was adopted only after fierce opposition. He founded the Society for the Cultivation of the Hebrew Language and Literature... He was no less benevolent than he was cultivated, and there is still in existence a charitable trust which was founded under his will.

• The London Jewish Chronicle (October 27th, 1905, p 11) wrote:

Moses Samuel was a very polished and genial man, very highly esteemed, who lived at Sparrow Corner, and afterwards Hammet Street, Monories. He then emigrated to Bath where he resided for many years till his wife died. Then he returned to London and dwelt with his eldest daugter, Mrs Solomon Cohen, in a large house with beautiful garden through which the New River at Canonbury ran. It is now the site of Alwyn Square.
A veteran of the congregation had the following quaint recollections of this ancestor... " I remember going with my father and mother as a child to see them at Canonbury and the old gentleman sitting in the corner with a wig. I remember his coming at the age of 98 to see my mother in the city, and he was very indignant when my mother wished to have him seen to the corner. He said: "No madam, I can find my way very well." After he had entered his 99th year he asked one day for a cup of coffee, and before it was brought to him, he had exired."
