  Electronics Home Study Courses

Capitol Radio Engineering Institute was founded in 1927 as a correspondence school by Eugene H. Rietzke, a Navy radio operator and his wife Lillie Lou Rietzke. Eugene was born in 1897 and he served in WWI eventually becoming Chief Instructor at the Bellevue Naval Radio Material School.
Five years later, in 1932, a residence division was opened, allowing students to reside at the school and study in laboratories. This facility remained at the corner of 16th Street NW and Park Road in Washington, D.C. for 30 years. In 1946, following World War II, the Institute was accredited by the Engineers' Council for Professional Development
