Around 1840, he established a settlement at Windhoek where he built a church for a congregation of between 500 and 600 in the area of the present-day Klein Windhoek suburb. He is further known for his road building activities in central and southern Namibia, particularly the one over the Auas Mountains to the south and the northern Bay Road from Windhoek to Walvis Bay.
