23 YEAR TOOELE RESIDENT DIES AT AGE 95
Pelayo Roger Dante de Gumuzio y de Cardenas, known by many as Roger Gumucio, died peacefully in his home surrounded by family on Monday, April 17, 2023 at the age of 95 years and 23 days. A graveside service was held Wednesday, April 19 at Grantsville North Cemetery.
Roger was born into a prominent family on March 25, 1928 in Cochabamba, Bolivia, son of industrialist Jose Luis Gumucio and merchant Maria Daria Cardenas, the sister of acclaimed botanist Dr. Martin Cardenas. He grew up the third of six siblings (excluding seven who died in early childhood) with many cousins among his large extended family. He was taught the importance of family, dignity, culture, and education, and often accompanied his botanist uncle gathering plants in the Cochabamba valley and surrounding Andean foothills.
After graduating from high school in 1946, Roger ultimately came to the United States to study English at Louisiana State University before transferring to the University of Missouri at Columbia, where he met high school junior Peggy Louise Ferril through the University’s International Students Club. They were married May 3, 1949 before Roger transferred to Northrup Aeronautical Institute in Inglewood, CA, renamed Northrup Institute of Technology when Roger graduated in 1953. Likely Bolivia’s first aeronautical engineer, while still a student Roger contributed to further development of the YB-49 flying wing concept (which inspired the B-2 bomber in 1970).
After graduation, Roger returned to Bolivia with his American wife and three-year old son, Dante. The President of Bolivia offered him to head up Bolivia’s first Civil Aeronautics Board, which Roger’s father insisted he refuse because it was conditioned on Roger’s joining the ruling MNR political party. Roger and his young family then returned to Columbia, Missouri in 1954.
Not yet a US citizen, and not able to get a security clearance to work on US military aviation contracts, Roger used his expertise in aircraft structural design to work for Butler Manufacturing Company, a Fortune 500 firm in Kansas City, MO. There he made major design innovations in the prefabricated steel agricultural buildings (“Butler buildings”) that replaced concrete and brick and mortar silos and processing facilities around the world.
During this time, Roger’s family lived in Kansas City, Independence, and finally Blue Springs, MO. In Independence, Roger became a US citizen and also joined the Church of Jesus Christ of Latter-day Saints (which Peggy had joined as a girl living in central Missouri), where he was baptized by Alvin R. Dyer, then President of the Central States Mission (and future Apostle and member of the First Presidency). Roger and Peggy also sponsored his four brothers and one sister in immigrating to the US from Bolivia, all of whom became US citizens with professional careers. Unfortunately, Roger’s mother and then father died before they could join their children in the U.S. Perhaps most importantly, in 1957 Roger and Peggy had their second son, David (later known to all as Gumby).
Roger left Butler in 1960 to become Vice-President of Miller Manufacturing Company in Modesto, CA, a Butler competitor focusing on the agricultural market in California and abroad. In 1960 while living in Ceres, CA he and Peggy had their only daughter, Dina. In 1961 he left Miller and returned to the Kansas City area where he started his own firm, Bulk Structures International, Inc. in 1963. For the remainder of the decade, Roger traveled extensively to market and install pre-fabricated steel agriculture and port facilities of his own

 design in Latin America, Asia, and Europe. He also acquired properties for development in and around Blue Springs and made contacts in Kansas City banking and mining sectors. In 1972, Roger and Peggy had their third son Darin.
Shortly thereafter, Roger changed his focus to mineral extraction and refining while being awarded numerous mining concessions in Colombia, South America. Roger and Peggy moved to Provo, Utah in 1973, and lived part-time in Provo, Blue Springs, and Columbia, MO through the rest of the decade. Ultimately, extensive international travel and financial pressures over a number of tumultuous years took a toll on his professional and personal life, including his marriage to Peggy which ended in the mid-1980s. Roger also had a daughter, Diana de Gumuzio, born in Cali, Colombia May 17, 1982.
Roger met Jennifer Jones in Provo in 1987 while Roger worked as a building inspector for the City of Provo. Their friendship ultimately turned romantic—“Oh, that voice,” remembered Jennifer--and they married on Sept. 9, 1989, followed by a honeymoon in California. They were sealed in the LDS temple in Provo, UT in 1991.
Roger worked in furniture manufacturing in Provo before venturing back to South America looking for new business opportunities. Roger and Jennifer lived in Istmina, Colombia from July 1992 through the fall of 1993 before returning to Salt Lake City, UT, where they bought a home in 1994. Jennifer would go on to work for the LDS Church and Walmart while Roger worked with an architecture firm and then the US Census Bureau. In April 2000, Roger and Jennifer moved to their final home in Tooele, UT, where Roger was able to return to his roots in aviation, joining his son Darin at Boeing Aerospace in Salt Lake City in 2004, where Roger retired (at age 85!) in 2013.
In March 2014, Roger took Jenny for an unforgettable three-week visit to his native Bolivia along with his brother Reynaldo, son Dante and his wife, Dante’s daughter Jesse, as well as Jesse’s family. Despite his age, Roger was the first one up every morning and the last one to bed every night! He greatly enjoyed showing Jenny and his family the land of his birth and reconnecting with beloved places and people.
Roger was preceded in death by: his two elder brothers John and Carlos, younger brother Mario, younger sister Maria Luisa, one sister-in-law, one niece, two nephews and a granddaughter; also his first wife Peggy Gumucio (15 June, 2021), and his second son David “Gumby” Gumucio of Grantsville, UT (March 12, 2023). Roger is survived by: his wife of 34 years, Jennifer Gumucio, son Dante Gumucio of Orange, CA, daughter Dina Petersen of Thousand Oaks, CA, son Darin Gumucio of West Jordan, UT, and daughter Diana Toro of East Windsor, New Jersey; and by 10 grandchildren, five step-grandchildren, 14 great- grandchildren, and two step-great grandchildren. Also surviving is his brother Reynaldo Gumucio of Rogersville, MO and his family; his sister-in-law Irene Gumucio of Monroe, New Jersey and her family; and the families of his late brother John and his late sister Maria Luisa.
Roger loved listening to music including: Argentine tangos by Carlos Gardel and boleros by Trio Los Panchos; more contemporary Latin singers like Vickie Carr and Julio Iglesias; and light classical and pops music by the Boston Pops Orchestra, Three Tenors, Josh Groban, and Andre Rieu. Roger also enjoyed watching PBS and documentaries on TV, and reading Spanish- language newspapers on the internet. A gifted basketball player in his youth, Roger later became a passionate “futbol” fan of the US men and women’s national teams, those of Argentina, Spain, and Brazil, and finally the Barcelona club team.

 Roger amazed, frustrated, inspired, and challenged his family, friends, and many acquaintances, and was truly an international “man of mystery!” At his best, Roger was a loving husband, father, and grandfather, as well as a devoted American and internationalist. He was incredibly hard working, resilient, and loving! He will be missed beyond measure!
