Brensing was born Nov. 14, 1916, on a farm northwest of Hudson, in Stafford County. After graduating from Hudson High School in 1934, he attended Salt City Business College, graduating with honors in 1936. He began working for the Stafford County Flour Mill Co. in 1937 as a bookkeeper, and continued working for the company for 73 years, reaching the position of president in 1986, which he held until retirement.
Built in 1909 by the Gustav Krug family, Stafford County Flour Mill has daily wheat flour capacity of 2,400 cwts and storage capacity of 3.4 million bushels, according to the Grain & Milling Annual 2013 published by Sosland Publishing Co. The company makes flour under the Hudson Cream and Diamond H label, as well as flour for private label distribution. During Brensing’s tenure as president, Stafford County Flour Mill introduced Hudson Cream Whole Wheat flour, taking advantage of the new hard white wheat varieties being grown in the area at the time. He also oversaw the remodeling and expansion of the mill in the early 1990s, including the installation of new cleaning and packing equipment.
Brensing was preceded in death by his wife, Zelda. Survivors include: two daughters, Elaine Brensing Woolf (Charles), Macksville, Kansas, U.S., and Jo Ann Brensing Beugelsdijk (Henry) of Hutchinson, Kansas, U.S.; and many grandchildren and great-grandchildren.
