Mortimer Epstein, Dictionary of National Biography… (1912)
“ Enjoying a large income, Mocatta was best known as a broad-minded philanthropist. Among the first questions that engaged his attention were the better housing of the working classes and the administration of charity in such a way as not to demoralise the poor. He was an active promoter and vice-president from its formation in 1869 of the Charity Organisation Society, and was chairman from 1901 of the Charity Voting Reform Association, with whose efforts to abolish electioneering in charity administration he was in fullest sympathy. ”
