His early mercantile pursuits were connected with the wool and woollen trades, and he took a lively interest in all measures likely to affect, them.
In 1825 William Huskisson, then President of the Board of Trade, invited the advice of Bischoff with regard to some proposed alterations in commercial policy, particularly a reduction of the duty on foreign manufactured goods.
Bischoff gave his opinion strongly in favour of freedom of trade, and the reasons he advanced had great weight with the minister in the proposal which he subsequently made in parliament.
[2] In 1836 he published an essay on Marine Insurances, their Importance, their Rise, Progress, and Decline, and their Claim to Freedom from Taxation, (octavo, 34 pages).
Bischoff, who married in 1802 Peggy, daughter of David Stansfeld of Leeds, carried on business as a merchant and insurance broker for many years in London, and died at his home, Highbury Terrace, on 8 February 1845 aged 69.
