Calvin Ephraim Larsen was born 31 May 1916 in Rigby, Jefferson, Idaho. He was the oldest of the 8 children born to Ephraim (Red) Larsen and Irene Pearl [Call] Larsen. Siblings: Thama [Larsen] Pugmire/Brown (1917-1997) Mathew Eric Larsen (1919-1987), Ross Call Larsen (1922-1997), Dorothy [Larsen] Rowland (1924-2013), Ardith Larsen (1926-1928) DeEsta [Larsen] Windley/Rousey (1928-2020) and Shirley [Larsen] Salvesen (1931-2020). He was given a name and a blessing on 2 July 1916 by August W. Ossmen in the Rigby, Idaho Stake. Calvin was consistent in his role as big brother throughout his life and he never hesitated to try and tutor his younger brothers and sisters in the ways of the world whether they were receptive to his instructions or not. During the early years of Calvin's childhood, he enjoyed the many activities that his uncles, who lived near by, introduced him to. They often had Calvin climb up on their shoulders and they would swim across the canals with him. Consequently, he learned to swim at a very early age. He started attending school in the fall of 1922 and he found school to be a rewarding experience for his bright and inquisitive mind. At the age of 8 years, he was baptized a member of the Church of Jesus Christ of Latter-Day Saints on 6 September 1924 in Rigby, Idaho by William A. Tall and confirmed the next day by John R. Sayer. His parents moved their family to Ririe, Idaho in 1925 where Calvin's father opened up his own barber shop. Calvin lived most of his life in the little town. Cal's new friends were a competitive group and he enjoyed this new challenge. There was never a lack of inventiveness on his part to find something to do. When Calvin was in the sixth grade, his father expanded his business to include a public bath. After school, it was Calvin's job to chop kindling and firewood and keep the wood box in the basement full so that his father could bank the fire for heating the water. That fall, Calvin worked in the potato fields picking up potatoes for half a penny a sack. This was very hard work for such a young boy, but he met the challenge out of necessity and was able to bring home potatoes to help feed the family throughout the winter. Calvin graduated from the Primary association of his church and was ordained a Deacon in the priesthood on 3 March 1929 by George W. Summers (George would later become Calvin's father-in-law). As a young man, Cal and his friends were fascinated with the little crystal radio sets of the era and they were determined to build one for their own use. They were successful in their endeavors. His interest in electronics did not end there and Calvin spent most of his life working in that field. Cal liked to fish and along with his father and brothers, he went on many boat trips down the Snake River. After his graduation from Ririe High School in May of 1934, Calvin worked for a time as the projectionist for the local movie theater in the evenings and during the day, he operated his own radio repair shop. Calvin's skill with electronics led him to seek employment at the Scientific Research Laboratories in Washington, D.C. where he worked until he was inducted into the Navy during World War II. After the war ended, Calvin continued to work in the scientific world and was one of those who paved the way to the age of Atomic energy. He spent approximately 15 years working for the Phillips Petroleum Company under contract to the Atomic Energy Commission and also operated his own radio/television repair shop in Ririe. Calvin married late in life, and the lady that finally won his heart was a childhood friend, Rose Irene [Summers] Ward. Rose had recently divorced her first husband and after a short courtship, Calvin asked her to be his bride. Rose accepted his proposal and the couple drove to Elko, Nevada where they were married on May 29, 1959 in Elko, Elko, Nevada. Calvin and Rose lived in Ririe at 354 Main Street and they had a happy marriage, but their happiness was short lived. One day while Calvin was at work, Rose went to visit her sister Helen who lived west of Ririe and then for some unknown reason drove on past her home only to run out of gas in her car in an area east of Ririe. She started to walk along the road that overlooked the Snake River Canyon and she slipped and fell to her death on 28 August 1959. Calvin was devastated and it was a very difficult time for him. He had lost the love of his life. Calvin left his job with Phillips Petroleum in 1968 and became an independent consultant in Instrument Technology. Electronics were not just a source of employment for Cal, he also thought of them as a form of recreation. He did enjoy other forms of recreation such as fishing, camping and going to the rodeo. He was even known to occasionally show off his skill on the dance floor. He met many eligible ladies who vied for his attention and he finally married again, this time to Eunice Hathaway, but the wedding cake lasted longer than the marriage and they separated a few days later. Later in his life, Calvin started having health issues and he was diagnosed with Colon Cancer. In July of 1991, Calvin's health started to deteriorate and after a few days stay in the hospital in May of 1992, he was taken into the home of Ross and Ruby Larsen where they cared for him. As his condition deteriorated, Ross and Ruby did not have the strength to meet his needs so his nephew Ron Larsen took over his care until Cal's health problems demanded intensive care. On 2 September 1992 Calvin placed himself under the care of the Good Samaritan Care Center in Idaho Falls Idaho. He passed away there, just five days later, on 7 September 1992. As per Calvin's wishes, his remains were cremated and then buried in the Ririe Shelton Cemetery next to his wife Rose.
