Described as a merchant when Isidor and Saara were born (1866-1867) and a mill owner when Friedeike was born (1868).

Owner and operater of a flour mill Gebrueder Staub.
MT notes that his gravestone is in Kattowitz cemetery, along with one for Arthur Staub who died in 1921.

MT gives his date of birth as 23/12/1830 while the date on his gravestone is "19 Tevet 5592" which corresponds to 23/12/1831; the former is probably a typographical error. Gmina Wyznania Mojżeszowego w Żorach 1511-1940 by Jan Delowicz gives 06/01/1830.

Similarly, MT gives his date of birth as 12/02/1905 but the date on his gravestone, "11 Adar I 5665", corresponds to 16/02/1905.
