Biography
Son of David Splitgerber (1683/5-1764), the founder of the banking firm Splitgerber & Daum of Berlin1. The young Splitgerber inherited a share of the bank from his father, but apparently "took no active part in the management of the business". He eventually sold his share to the Schicklers in 1795.2
In 1765 he was named Master of Hounds to Prince Ferdinand of Prussia (1730-1813), and in 1789 he was ennobled by Friedrich Wilhelm II.3
Life with Boswell
Boswell met Splitgerber (refered to as young Splitgerber) in Berlin on July 6, 1764. He described him as "a good bluff dog [who] has been three years in London." He spent the rest of the day in his company, and was "firm and gay and sound as ever".
