Hyslop, Adin Edwin's Obituary
Born on May 16, 1943, in El Paso, Texas, Adin was the first son of U.S. Army Major James Robert Hyslop and Mildred Teresa Woods. He grew up in the border town of Del Rio, sharing a busy home with his parents, grandmother, two younger brothers and sister. From an early age, Adin balanced childhood mischief with a deep sense of care and loyalty to his family—qualities that would define him throughout his life.
Adin attended Peacock Military Academy, known as the “West Point of Texas,” where he thrived academically and discovered a lifelong love of science and mathematics. He went on to attend Southern Methodist University from 1961 to 1970, earning his B.S., M.S., and Ph.D. in Electrical Engineering—an achievement that reflected both his intellect and his persistence.
After graduate school, Adin met his first wife, Deborah Lund. They married and welcomed their son in 1974. The following year, Adin began teaching Mechanical Physics and Electrical Engineering at Texas A&M University in College Station, and in 1978 their daughter was born. In 1979, Adin joined Texas Instruments’ Memory Design Team in Houston, and soon after, their third child—a daughter—was born.
While building a distinguished career, Adin remained deeply engaged in family life.
He coached Little League Baseball, attended soccer tournaments, gymnastics meets, piano and ballet recitals. His work took him around the world but he always returned home for his family. Ever the humorist, he would often wake the kids up cheerfully shouting, “Time for school! Motivate! Exponentiate!” — a math joke not many teenagers find very funny at 6am on a school day. Family road trips to the Grand Canyon, camping in Yellowstone National Park, skiing in New Mexico, and hiking among the lava flows in Hawai’i instilled in his children a lasting love for nature and adventure.
In 1988, the family moved to Dallas, where Adin led semiconductor design and manufacturing teams at Texas Instruments. His work earned multiple patents and awards and made meaningful contributions to computer science and engineering. Outside of work, he was happiest with a dog by his side, immersed in the study of NASA Space Exploration, watching Star Trek: The Next Generation, and passionately following the Dallas Cowboys.
In 1994, his contributions to the development of CMOS detectors led to a data collecting expedition at the White Mountain Research Center in support of cosmology research for the University of California. But among his proudest professional moments was a 1995 mission funded by the U.S. National Science Foundation aboard the legendary Nathaniel B. Palmer Icebreaker Ship in Antarctica, supporting critical oceanic and climate research.
On February 14th, 2005, Adin met Pamela Bonifacio, while traveling for work in Japan. His determination to be with her led him to the Philippines, where they married in 2008. Together, they built a life in Dallas. There, Adin eventually retired and devoted himself fully to his faith, his wife, their daughter, his mother-in-law, extended family and grandchildren—once again filling his days with Little League games, recitals, Capoeira classes, church, family, and school events.
Above all else, Adin loved his family. He will be remembered not only as an accomplished scientist, but as a devoted husband, father, grandfather, and a steady, loving presence in the lives of those who knew him.
Adin is survived by his beloved wife, Pamela Hyslop; children Trevor Hyslop, Amanda Hyslop, Brie Hyslop, Kathleen Aguilar, Mikee Bonifacio; grandchildren Luis Pillas, Lloyd Pillas, Mary (Sophie) Hyslop, Sienna Hyslop-Driegert, Isaac Hyslop, William Hyslop-Driegert, Birdee Hyslop, Aria Anzures, Coyo Hyslop; siblings James Hyslop, William Hyslop, and Elizabeth Hyslop.
A memorial service celebrating Adin’s life will be held on January 17 at 10:00 a.m. at Restland Memorial Chapel, 13005 Greenville Avenue, Dallas, Texas 75243. An optional burial ceremony will follow at 12:00 p.m., with an optional reception at 1:00 p.m.
In lieu of flowers, the family asks that donations be made in Adin’s memory to the Alzheimer’s Foundation of America or the U.S. National Science Foundation.
