The oldest of nine, Al was born Nov. 3, 1941, to Pablo and Ruby Roybal and raised on Rancho Las Lagunas, the family dairy farm begun in 1946 in Nambe, N.M. Al graduated as valedictorian from Pojoaque High School in 1960, received a B.S. in chemical engineering from New Mexico State University in 1964, and then spent six months living on farms in Ireland as part of a 4-H program. He also received an M.S. in chemical engineering from the University of Delaware in 1969. He began a 28-year career with DuPont as a research scientist in Delaware in 1965. He had first been introduced to the East Coast during a 4-H high school trip to Washington, D.C. At DuPont, he worked primarily on polymers at the Experimental Station in Wilmington, Del., and at plants in Texas, North Carolina, West Virginia and Tennessee, and developed a process to recover and sell byproduct acetonitrile. After retiring from DuPont in 1993, he consulted in Chicago, Philadelphia, Maryland and New Jersey before beginning a second career in 2003 as an environmental engineer regulating air quality for the State of Delaware. He worked full time until October 2012. He is survived by son Peter Roybal, of New York City; daughter Jessica Roybal, MD, and grandson Asher McCoul, of Seattle, Wash. (Edward McCoul, MD); former wife Ann Roybal, of Newark; siblings Roberto, Rick (Judy), Paula Sanchez (Gary), Alfred (Orlinda), Jim, Anna Price (Thomas) and Paul (Mark Anstadt); and a large and loving family of aunts, uncles, cousins, nephews and nieces. His brother Don preceded him in death. Memorials will be held in Delaware and New Mexico in the spring; contact p.roybal@gmail.com for details. The family requests donations to Pancreatic Cancer Action Network at pancan.org and that you buy a stranger an ice cream cone or cup of coffee, as Al enjoyed doing.5.
