Tucson was “born” the year before the Declaration of Independence was signed. Find out what life was like for our city’s founders when Tucson historian John Lown talks about Tucson’s beginnings in celebration of Tucson’s 239th birthday on Aug. 20.

The presentation will take place at 1 p.m. in the Inn lobby, 5830 N Fountains Ave., just south of and separate from the main building for The Fountains at La Cholla.

Lown has 3,000-plus lecture hours with the Arizona Historical Society, where he volunteered for 24 years. He has lived in Tucson more than 66 years, graduated from Tucson High School in 1949 and served in the Army for 20 years.

Lown first became fascinated by Tucson history when his Boy Scout troop made its own costumes and performed traditional American Indian dances around town and at Tucson rodeos. These days, Lown enjoys bringing history alive as a participant in re-enactments of the Mountain Men who arrived at El Presidio de San Agustín de Tucsón, established Aug. 20, 1775.

During his Aug. 20 presentation at The Fountains, where Lown lives, he will share artifacts and personal items as well as his knowledge of Tucson’s early settlers and their way of life.

For those interested in delving deeper into the subject, starting in September Lown will teach a free course about the Mountain Men as part of Watermark University’s fall curriculum.

Watermark University is the brainchild of Watermark Retirement Communities, operator of The Fountains at La Cholla. Through its ever-evolving curriculum taught by all-volunteer faculty members, Watermark University seeks to connect residents and guests with diverse opportunities to engage in mind and body fitness for life.
