Ursuline Academy of Dallas turned 147 this week.

Students, faculty and staff celebrated Founders Day on Feb. 2, remembering the day when six sisters from the Galveston Ursuline community arrived at a four-room house in Dallas. In that house, the six women would live and teach.

Within weeks of the sisters’ arrival, the original seven students grew to 50.

Today, the more than 850 high-schoolers who attend Ursuline, the oldest continuously operating school in the city, still pledge Serviam, which means “I will serve.”

Many prominent public figures have graduated from the school, including philanthropist Melinda Gates and former Deputy National Security Advisor for Strategy Dina Powell.

A couple other private schools in Preston Hollow have also been around for more than a century.

The institution that later became St. Mark’s School of Texas in 1950 was founded by M.B. Terrill as the Terrill School for Boys in 1906. Terrill invited Ela Hockaday to come to Dallas, where she founded The Hockaday School for Girls in 1913.
