The Executive Towers, completed in July of 1963, is listed in the National Register of Historic Places as the work of a master, Phoenix designer Alfred Newman Beadle. At the time, Al Beadle was the designer in the firm of Alan A. Dailey and Associates, the architect of record. Upon completion, the $4.5 million, 22-story Executive Towers became the tallest building in Phoenix and the State of Arizona. Executive Towers is a strong statement of mid-century Modernism, unique among other Phoenix architecture of the period, and a pivotal building that established the career and reputation of Al Beadle as a prominent Modernist designer in Arizona. Known primarily for the residential architecture that symbolized his Phoenix career subsequent to the Executive Towers, Beadle earned national acclaim both as a result of Executive Towers, and publication in the "Case Study" series of Art and Architecture magazine in 1963 that established Beadle as a major architect of Mid-century Modern buildings on the national scene.
(Note, Al Beadle did not become a registered architect until 1967, but he is recognized as the designer, as documented on the original drawings for Executive Towers.)
