Little biographical information is readily available about this author beyond bibliographic records, which identify him as Emil Aldren Johnson (born 1875).
He is known for Furniture Upholstery for Schools (1919), published by The Manual Arts Press in Peoria, Illinois. The book presents upholstery as a hands-on school subject and explains methods, materials, and projects in a straightforward way for classroom use.
The text also identifies him as Emil A. Johnson, B.S., A.M., and as an assistant professor of manual arts at Bradley Polytechnic Institute. That background fits the practical, instructional tone of his writing, which was clearly meant to help teachers and students learn useful workshop skills.
