Louisan E. Mamer (1910-2005) was born on August 28, 1910 to Louis H. and Anna Mary Elizabeth Mies Mamer. She graduated from the University of Illinois, College of Agriculture with an AB in 1931. Mamer begin her government career with the Tennessee Valley Authority (TVA), moving to the Rural Electrification Administration (REA), United States Department of Agriculture (USDA) in 1935. The REA was one of President Franklin Roosevelt's programs described collectively as the New Deal. The REA's goal was to bring affordable electricity to rural America. Electrification brought prosperity and an elevated standard of living to rural areas, but initially there was a great deal of ignorance about electricity in its applications and uses. Mamer was hired by the REA as a Home Electrification Specialist, or "demonstrator," to educate people in the uses of electricity.
Mamer was based at the REA headquarters in Washington, DC but traveled extensively throughout the Midwest performing demonstrations of electrical appliances, planning and teaching "training schools" for rural electrical co-op advisors, demonstrators, and home economics teachers initially in the states of Iowa, Illinois and Nebraska. This traveling show came to be known as the "electric circus." Her first show was in the Maquoketa Valley Rural Electric Co-op near Anamoso, Iowa. Mamer described the process in a 1975 interview: "We would usually move into a town over the weekend. Having made the move and set up the tents [two large circus tents] and gotten ready for the show during the daytime, say, on a Monday, that night we would have the home electrification specialist (which was my job) demonstrate lighting equipment. I believe the next morning we had a laundry equipment demonstration at about 10 a.m., and in the afternoon, we demonstrated small appliances and some kitchen and laundry planning along the way. The last evening, the home electrification specialist conducted a big cooking duel between two local men. That was a highlight of the whole program." 
The electric circus was discontinued in 1941, a victim of WWII gas shortages. Mamer continued educating rural America with the Electro-Economy Tour designed to help the war effort. This was also discontinued due to WWII shortages. After the war, Mamer began traveling and demonstrating again while also developing training courses for the REA and REA co-ops nationwide. Through her demonstrations and training materials, Mamer was not only teaching rural America in the uses of electricity but in a lifestyle reflecting the goals of the New Deal - a better life for average Americans. Mamer's largest audiences seem to have been rural housewives but men were included as well, especially in the "cooking duel". Mamer identified with these women and from her notes and interviews she seems to have firmly believed in her mission to better people's lives through electricity.
In a 1948 article for
Practical Home Economics
magazine, Mamer briefly described her background and work:
My background is rural; locale, southern Illinois. As I grew, 'college' like 'mama's bank account' was always with us, and we worked to get the money for it --selling pecan meats, mowing, raking, doing everything but plowing for the same pay as the hired men. Finally I had almost $1,000, a fashionable suntan, unfashionable broad shoulders and a "harrowing" walk that served me well in getting about at the University of Illinois.
That first year I planned to become a writer, but by my sophomore year I decided that I should learn something to write about. So I spent my last three years and four summers more becoming a home economist and satisfied my craving for writing on The Daily Illini and the Illinois Agriculturist, college sheets of which I was woman's editor.
My background was, as astrologers would put it, propitious to home economics. My mother had already mothered one family of seven brothers, and she operated on a big scale. We butchered; we churned; we canned; we baked bread; we had two acres of garden, fruit, chickens and a milk route. All this-sans electricity, sans running water.
When I started teaching, an all-electric foods laboratory was a rarity, but I got one and was very proud of it. I also got a great deal of experience which came in handy when I left teaching to take a job in Washington writing for NYA.
REA was so new then that home economics hadn't entered the picture, so I went in as a writer. In 1937, after a training period in TVA, REA sent me to Illinois, Iowa and Nebraska as a regional home economist. Except for being lent briefly to WPB I've been in REA ever since.
My secret ambition is to build a modern house; furnish it modern and Chinese; equip it all-electric and with a husband guaranteed not to wander; operate the whole arrangement at enough profit to provide myself with all the secretarial and other help I would like to have to do my job the way I would like to do it and write besides. 
Mamer married Arthur C. Hagen (1911-2000), an REA electrical engineer, on March 20, 1954. She devoted her working life to the REA retiring in 1981. Mamer died in Washington, DC in December 2005.
