Isaak Iselin, 1783-1841, businessman and banker, born in Basel, settled in New York in 1801. Worked his way up the trading house of LeRoy-Bayard & McEvers, where he was a partner 1808-1815. In 1815 became a partner of DeRham-Iselin & Moore. Returned to Basel in 1835, but was forced to spend another two years in New York when his business suffered serious losses as the result of a fire. He returned to Basel definitively in 1838. His son Adrian Georg Iselin (1818 - 1905) founded the bank A Iselin & Co, had interests in railways and mining, and spent much time and money on philanthropic works.
