In 1943, he founded the Humanity Benefactor Foundation and University of Lawsonomy in Des Moines, on the site of Des Moines University, to spread his teachings and offer the degree of "Knowledgian", but after various IRS and other investigations it was closed and finally sold in 1954, the year of Lawson's death. Lawson's financial arrangements remain mysterious to this day, and in later years he seems to have owned little property, moving from city to city as a guest of his farflung acolytes. In 1952, he was brought before a United States Senate investigative committee on allegations that his organization had bought war surplus machines and then sold them for a profit, despite claiming non-profit status. His attempt to explain Lawsonomy to the senators ended in mutual frustration and bafflement.
