History
According to the Engineering and Technology History Wiki, the Tucson IEEE Section was formed in 1953 as a subsection of the Phoenix chapter of Institute of Radio Engineers (IRE). IRE was formed in 1912 to focus on Wireless Radio.
In 1 April 1956 IRE Tucson became a full section.
It then became an IEEE section in 1963 when the IRE merged with the American Institute of Electrical Engineers (AIEE). AIEE was formed in 1884 to host foreign electricals at the International Electricals Exhibition.
