Lief David Frederick passed away peacefully on April 25th, 2025, at the age of 73. Born on August 16th, 1951, in Pomona, CA, Lief was the second of four children born to Dr. Paul and Emmy Frederick. In 1960, they settled in Claremont, CA where he would remain a lifelong resident. Lief carried a deep pride in his Italian heritage, often recalling fond memories as a child of visiting his Italian immigrant grandparents, Delfina and Evasio Brusasco in Tuolumne, CA and traveling through Europe as a teen with his family. As a young man, he made cherished trips with friends to visit his cousin Maurizio in Italy, especially treasuring his time in Alba, his mother’s hometown. A gifted musician, Lief’s extraordinary talent as a bass player and his soulful touch on the 12-string guitar could move hearts and bring his listeners to tears. He was a fixture in the Claremont music scene for many years. It would be music that would bring him together with his loving wife, Valorie. They met performing USO tours and would perform together for years to come. They married in 1975 and would go on to have three children together: Lief David II, Taylor, and Austin. Lief was also a talented craftsman, skilled in painting and home restoration. While he would keep this profession for many years, it was other activities he was most proud of. While Valorie taught music at Oak Tree Day School in Pomona, Lief would perform at her students’ performances, which included their children Lief and Taylor. He participated in painting The Pomona Arts Center Mural, which featured Valorie, son Austin, and granddaughter Ashlyn. Lief was also a proud volunteer coach for Pomona Valley Special Olympics, where he coached Austin and other amazing athletes in track & field, as well as other events. Above all, Lief cherished his role as grandfather. Watching his grandchildren grow and thrive in their many activities, from color guard, band, soccer, and beyond. It brought him immense joy. In his later years, one of his favorite treasures was a digital picture frame that played an endless loop of pictures of his grandkids (and his cat Hobbit). Lief is survived by his wife of 50 years, Valorie Frederick, and Children: Austin Frederick, Taylor Marie and Lief Frederick II (Noelle Frederick); Grandchildren: Ashlyn, Kai, Dilyn, Hayden, Eden, Bella Jaffri (Robert Jaffri) and Rudie; Siblings: Paula Frederick, Galen Frederick, and Victoria Brown. A celebration of Lief’s life will be held at a later date.
