American Television Institute
The American Television Institute (ATI) was run by U. A. Sanabria, who was a pioneer in mechanical television. In the mid 30s he
founded the school, which trained students through the 50s. There were a
number of schools with television
programs before World War Two.
ATI students made monscopes and CRTs as part of their training.

ATI Telephone Television System
This system was manufactured by ATI in 1936. It was demonstrated all over the country in department stores, fairs and auto dealerships. Here are some newspaper articles describing these demonstrations (courtesy of Wayne Bretl).

They provided a system to Duke University in 1938 |
ATI made these 2 way television units in relatively large
quantities. Many were sold to colleges and universities. The
first lesson in ATI's 1937 television correspondence course says
that systems were sold to DePaul, Armour Intstitute of Technology
(Chicago), Michigan College of Mining and Technology (Houghton),
The Drexel Institute of Technology (Philadelphia), University of
Louisville, South Dakota State College (Brookings), Fenn College
(Cleveland), and Louisiana State University, at a cost of $500
each. It is interesting that they were able to sell mechanical
systems in 1937, well after all mechanical broadcasting had
ended. |

ATI also provided equipment to the U. S. Military Academy at West Point,
New York, for reception of the transmissions from New York City. Below
is the receiver, which also serves as an oscilloscope. Similar units
were used in ATI's training program. A similar system was made available to students at the Institute, called the "Double Electronic".

| My dad Bill Steed went to an ATI school in Chicago too in February 1939. From letters (post cards) back home, it sounded like he left early but did spend about 2-3 weeks in Chicago. he mentions Mr. Sanabria in a couple of the letters. From these letters, it sounds like he had it at home, configured it and then transported it to Chicago for the class.

From the above photo, the top unit appears to be the receiver (monitor), similar to this later model. The bottom unit is the transmitter. It doesn't use a camera tube, but uses a monoscope, a tube that has a permanent image on it: http://uv201.com/Tube_Pages/monoscope.htm. ATI had its students make monoscopes as part of their studies.
Here is another unit built by Steed, showing the ATI photocell.

Tom Stanonis sent us a document about the 1949 commencement ceremony, His father Alphonso Stanonis was one of the graduates. He also sent the Curriculum for the Degree Bachelor of Science in Television Engineering with his father's grades annotated on it. It probably dates from 1946-1949. Here is his identification card
