Roger was born on April 18, 1935 in St. Louis, Missouri. His doting parents were Warren and Florence Bopp (nee Kruegel). The Bopps enjoyed spending time outdoors in rural Missouri and northern Arkansas with their family and friends. Roger was a Boy Scout and loved his faithful companion, a rat terrier named Nick.

Roger served in the U.S. Navy from 1954 through 1957 as an Electronics Technician at the submarine base in the Pearl Harbor territory of Hawaii. He went on to study Electronics Engineering at the Capitol Radio Engineering Institute in Washington, DC. Together these experiences prepared him for his career in computers, field engineering, and service planning.  

While working in Manhattan, Roger found his dream girl - a well-traveled, beautiful blonde, Marion Unverzagt, who became his wife in 1963. Roger's careers at Honeywell Corp and Harris Corporation took the couple to Sierra Vista, AZ, Boston, MA, Kailua, HI, Honolulu, HI, Fresno, CA, Newark, CA, Cerritos, CA, Melbourne, FL, and Carrollton, TX during their 44 years together. Along the way, they raised three children: Andrew, Diane, and Jeffrey. Growing up as an only child, Roger loved being a father to three and a part of Marion's larger family. He remained close to the Unverzagts since Marion's death in 2007.

While living at Heritage Ranch in Fairview, Roger met Carol Boone. Carol brought joy and liveliness to Roger's final years through traveling and spending time with their friends. Unfortunately, cancer restricted Roger's activeness, but not his sharp mind. Volunteering allowed Roger to share his lifelong interests of fossils, geology, and engineering as he volunteered at Heard Natural Science Museum & Wildlife sanctuary and tutored Allen GED students in Mathematics. Roger loved to fish, whether salt or fresh water. He frequently directed fishing competitions at Heritage Ranch and taught many of the residents' grandchildren how to fish in the neighborhood's lakes.

All three of Roger's children possess his mathematical ability and his love of exploration. Roger's engineering mind lives on through his son, Andrew (wife, Kathya). Roger's attention to detail lives on through his daughter, Diane (husband, Bryan; children, Chase and Emmeline). Roger's sense of humor lives on through his son, Jeffrey (wife, Marlene; son, William).  

Roger and Marion's children miss them indescribably. In memory of Roger, the family requests that you tell jokes frequently, enjoy a slice of key lime pie, partake in a rowdy game of Scrabble, continue learning, and travel as much as possible - especially to the place he loved so much, Hawaii.

With great love, admiration, and thankfulness, we say "Aloha" to Roger on August 6, 2015.

Memorials may be made to The  American Cancer Society, Dallas Paleontological Society, or Heard Natural Science Museum & Wildlife Sanctuary. Mahalo!
