W. Caleb Glazener became assistant director of the Foundation in 1955. He and Clarence Cottam lived in rented homes in Taft for several years during the construction phase of the Foundation headquarters and residences (1958-1960).

If Clarence Cottam was the ‘long arm’ of the Foundation, Caleb Glazener was the on the ground, ‘nuts and bolts’ man. Glazener came up through the ranks of the Texas Game and Fish Commission (Texas Parks and Wildlife Department), starting his career as a coyote trapper (coyotero) in south Texas. When hired as the Foundation’s first assistant director, he had achieved the rank of Chief of Wildlife Restoration for the state of Texas. If there were ever a perfect match of directors for the formative years of the Foundation, Cottam and Glazener were that match. Cottam was active in the conservation community and made a name for the newly-created organization; Glazener stayed home and conducted the day-to-day activities of the Foundation.

Glazener accepted the position of director somewhat reluctantly, as there was no one else standing in the wings ready to take over. He never really believed he was a person of the stature of Cottam, nor that he had the experience and recognition to become director. Yet his steady hand at the helm was exactly what the Foundation needed at the time. The programs developed by Glazner and Cottam gave the Foundation a reputation for conducting wildlife research that was on the leading edge of research being conducted in the United States, if not the world. The process they developed of selecting only the top wildlife students for Welder Fellowships paid off and Welder graduates are in some of the top wildlife conservation and management positions in the country. So, Glazener saw no reason to change the Foundation’s programs when he became director.

In the months preceding Cottam’s death in March 1974, he and Glazener had discussed and the WWF trustees had approved the hiring of a range ecologist. The person at the top of their list to fill the position was Lynn Drawe. Drawe was hired in early summer 1974, and began work with the Foundation on July 15 of that year.

In the final years of Cottam’s tenure, the trustees directed that he spend more on student fellowships in order to meet the IRS requirements for tax exempt foundations, which almost doubled the number of fellowships the Foundation was offering. However, following Cottam’s term, Glazener and Drawe had to wind down the number of projects to match the fellowship budget with available funds. At about this same time the Caesar Kleberg Trust granted considerable funds to WWF for several years. These funds also soon dissipated when the Caesar Kleberg Wildlife Research Institute was created in 1981 at Texas A&I University. Glazener dealt with these major funding fluctuations with style and finesse.

Glazener was an individual who never sought the limelight. Throughout his tenure as director he quietly and effectively conducted the affairs of the Foundation with great confidence. Caleb Glazener retired from the Welder Wildlife Foundation in December 1979.
