Angerstein’s father came to England from his native Russia as a youth, became an underwriter at Lloyd’s, was naturalized in 1770 and after a long partnership with his father, acquired a fortune as a loan contractor during the French revolutionary war.
At his next successful nomination (in January 1835 for Greenwich) he reminded his hearers that he had once sat for a nomination borough for which the full equivalent had been paid, but it was with feelings of pain he did so, as he objected to such a system of representation. He now described himself as a constitutional reformer, ‘a Radical to a certain extent, but no Destructive’.
He died 8 Apr. 1858, aged 84.
