As director of Louisiana Wildlife and Fisheries, now the Louisiana Department of Wildlife and Fisheries, Glasgow succeeded the original McKeithen administration appointee, Clark Milliken Hoffpauir of Crowley in Acadia Parish. Glasgow expressed a desire to separate natural resources policies from partisanship, but he left the McKeithen administration after just over two years because of renewed political infighting. Outdoor enthusiasts in Louisiana, such as fisherman, hunters, trappers, campers, hikers, and birdwatchers, viewed him as their champion. He served on twenty advisory board and commissions, including the Boy Scouts of America. As assistant secretary of the interior in the Nixon administration, Glasgow had been recommended to Secretary Walter Hickel by David C. Treen, who had just lost his third campaign to unseat Hale Boggs in Louisiana's 2nd congressional district. Treen was later the first Republican U.S. Representative, from Louisiana's 3rd congressional district, and governor of Louisiana since Reconstruction. In that role, Glasgow stressed that land-holding companies must conserve natural resources. Coincidentally as assistant secretary, Glasgow hired young Robert J. Barham of Morehouse Parish in northeastern Louisiana, the former director of the Louisiana Department of Wildlife and Fisheries, to work at Glacier National Park in northernmost Montana. In an interview published in 2008 in The Monroe News-Star, Barham said that his youthful experience at Glacier park was "amazing. I was mentored by people like my dad and Glasgow, who knew the importance of our natural resources." Louisiana has of wildlife management areas. When he returned to LSU for his final decade in 1971, Glasgow assumed the title of Assistant Director for Wildlife and Fisheries. He served as major professor for 44 graduate students and sat on the committees of 159 graduate students. He was affiliated with seven professional organizations and a member of four honorary societies. He taught eight wildlife courses and authored thirty-two scientific papers. On June 30, 1980, he retired from LSU. A retirement celebration was held on July 16. Glasgow died eighteen days later on August 3 at the age of sixty-six while he was in San Jose, California, visiting relatives and attending a board meeting of Williams, Inc., a large landowner in south Louisiana of which he had been named company vice-president. Glasgow and his wife are interred at Resthaven Gardens of Memory and Mausoleum in Baton Rouge. In 2008, Glasgow was posthumously inducted into the LSU Hall of Fame.
