My kids used to attend school there 35 years ago, but the high school was named John Foster Dulles High School. They must have changed the name after this gentleman graduated.
OK, Dulles wasn't all that new, from their site:
The Fort Bend Independent School District was formed on April 18, 1959 by the consolidation of the Missouri City Independent School District and the Sugar Land Independent School District. At that time the facilities consisted of 2 elementary schools, a junior high, a senior high [Sugarland HS??], and two football stadiums.
A site was immediately purchased on Dulles Avenue (at that time known as Lester Road) and the construction of the Administration Building and John Foster Dulles High School began. Fort Bend ISD had its first graduating class in 1960. The first class actually graduated from the present Dulles High School in 1962. The class of 1963 was the first graduating class from Dulles High School to spend an entire year at the new facility. Many people consider Dulles High School to be the first high school in Fort Bend, since it was the first one built by the district under this new name.
