[1] After moving to Minnesota, where he built the North Star Woolen Mill at St. Anthony's Falls, he served on the University of Minnesota Board of Regents from 1871 through 1879, and was a founding Trustee for Lakewood Cemetery.

[1] He abandoned his failed business interests in Minnesota to try his luck out West and, in 1880, paid a visit to the Great Falls of the Missouri River and quickly recognized their potential for producing hydroelectric power.

Despite this setback, Great Falls became a major center of trade for area farmers and ranchers, and its dams on the Missouri River contributed power for ore processing and grain milling industries.

Some time later, Theodore suffered a similar health problem and was also sent to Warm Springs, where he died.
