Identity:
Louis Herrman was a partner in the firm of artists' suppliers Gilby and Herrman. His wife, Isabel, was born about 1840 in Lewisham.
Life:
Hermann appears to have left Gilby by 1878 when he had an art gallery at 60 Great Russell Street, Bloomsbury (#08878). Around this time Herman lent JW some money, a loan that was negotiated through Charles Augustus Howell. However, JW was unable to keep up with repayments (#02778). He was one of the creditors listed in the records of the London Bankruptcy Court on 7 May 1879 (#11711). Indeed, in 1881 he was listed in the Post Office Directory as a 'picture dealer'. However, in the City of London Directory for 1900 he was listed as a partner in Gilbey and Herrmann, printing material manufacturers, at 7 Plum Tree Court.
