Jacobi attended the University of Minnesota from 1927 to 1930, where he got his literary start contributing to campus magazines.

"MY first serious interest in science fiction began, I suppose, during college days at the University of Minnesota where I tried to divide my time between rhetoric courses and the geology laboratory. As an underclassman I was somewhat undecided whether future life would find me studying rocks and fossils or simply pounding a typewriter. The typewriter won.

Traveled a spell ; fooled about with telegraphy, both wireless and Morse for another spell; then turned to writing fiction.

Thirty, unmarried, and my hobbies include studying the night sky with a 60-power glass, continuing contacts with friends now located in jumping-off spots of the South Seas and Malaysia, and saving old tobacco tins."
