D. T. H. Mac Kinnon was a capitalist, entrepreneur and inventor. Among his business ventures were a pulley factory, excelsior mill for which he invented a more efficient knife and paper mills. Duncan was born in 1852 in England, the son of Capt. Lauchlan Mac Kinnon of the Royal Navy. Captain Mac Kinnon met former Wisconsin territorial governor, James Doty in 1849 while in Washington D. C. and traveled with him to Menasha. The captain loaned Doty money with the governor's land holdings as security. The upshot of it all this was the governor defaulted and Mac Kinnon acquired land in Menasha. In time the captains sons Falkland and Duncan came to this county and were managing things in Wisconsin. Falkland moved on to Wausau and then Wisconsin Rapids and Duncan made his fortune in Menasha.
