After the death of his father in 1870, Sigmund Pickert and his brothers, Max (1836-1912) and Julius, continued the business. Sigmund counted many prominent collectors and museum curators among his clients, such as John Charles Robinson and Henry Cole from the South Kensington Museum – now Victoria and Albert Museum in London.

Sigmund Pickert set up a foundation with 30,000 marks for charitable purposes and to enhance the beauty of the city of Nuremberg. Nor did he forget his birthplace; he left the city of Fürth 20,000 marks upon his death.

Adolphe Schloss acquired a series of 12 works by Flemish painter Abel Grimmer (Schloss German no. 66-77/ French no. 90/1-90/12), which came from the Pickert Galerie in Nuremberg.
