Thorleif Frederik Schjelderup graduated as
cand.jur. in 1882, but concentrated on a business career as he in 1884 entered the family company
Ludwigsen & Schjelderup. He eventually became the single owner of the company, which was nationally leading in the grain and flour business. He was also the major shareholder of the forestry and timber company
Enso-Gutzeit until 1919, and a co-owner of the iron- and steelware factory
Christiania Spigerverk. His son Gunnar took over here in 1926. ==References==
