Description: Practical Technical Training In Radio Television & Allied Electronics Training Manual For consideration is this vintage training manual or lesson book titled “Practical Technical Training In Radio Television and Allied Electronics” from National Schools located in Los Angeles, California. The school was established (after the arrival of the automobile) in 1905, and at that time offered training in auto repair. Mr. L. J. Rosenkranz was the President of this international school that taught several correspondence courses including electronics (how to repair a radio). This training manual or lesson book has heavy plastic front and back covers and is circa the early to mid-1940s. It is bound with the original shoe lace type string and measures 8¼ inches wide, 11 inches tall and 1¼ inches deep.

NOTES ABOUT THE SCHOOL: As technology advanced, new schools were added, including programs in aviation, radio repair, and radio broadcasting. In the mid-1930s when Diesel engines became practical, the school had to expand again to accommodate another in-flux of students. During World War II, the school trained hundreds of soldiers as radio technicians, electricians, and automotive mechanics. The school grew so large and so fast that in late 1942, the school and its officials were indicted in Federal court for trying to defraud the government, but after a three-day trial, the officials were acquitted of the charges because no act of wrongdoing was discovered. After the war ended, enrollment swelled even more as returning soldiers used their G.I. benefits to pay for education. As the post-war economy regained a confident consumer focus, there was more demand for automobiles—and people to repair them. Television was another growing post-war industry, and the school programs in television repair. Classes in home appliance repair and heating and air conditioning were also implemented. In late 1959, the name “National Schools” changed to “National Technical Schools (NTS). An Encino-based company, United Education and Software (UES) bought NTS in late 1985. There is an interesting thread under postcardhistory dot net where a number of people from other countries state they took these courses.
