Born in Casper, Wyoming, David G. Fox Jr. graduated from Highland Park High School and attended Texas A&M University for a year and a half before serving as a Navy pilot in World War II. After the war, he continued his education at Southern Methodist University but left to begin a sales career with a fabric company. In 1947, his father organized the Fox and Jacobs Construction Company with brothers Ike and Joe Jacobs, and after his father's death in 1949, Fox, though inexperienced in home building, agreed to become the Jacobs brothers' partner. In the 1950s, the company focused on putting customers and employees first while continuing its education and studying new industry innovations. Its homes, described as having a California look with a Texas practicality, were aimed at middle-class young buyers. In 1973, a search for new markets brought Fox and Jacobs to the undeveloped area north of Carrollton, where they gradually acquired more than 3,000 acres. In 1974, about 2,500 people visited the new homes at the unveiling of The Colony, and the first families moved in that October. Fox and Jacobs then helped the new community obtain basic services by building, equipping, and donating the fire station and adding traffic lights, retail centers, and parkland. Fox was honored in 1983 as the founder of The Colony and was named 1984 Dallasite of the Year. After retiring, he served as Dallas County Judge and chaired many civic, philanthropic, and political organizations. He is remembered as a leading figure in Texas home building.
