Clem was born March 4, 1910 near Rapid City to John & Anna Bourquin who immigrated to the US from Switzerland. He had an older sister, Alice, and a younger brother, George. His father later homesteaded in the Badlands on the Quinn Table where Clem spent his formative years. There he helped his father farm, raise cattle, and break wild horses. His love of horses and the outdoors continued throughout his life. As a young man, Clem spent several years working on his Uncle Bill Lehmann's ranch in Rapid Valley where he lived with the family. Clement came from a family of Swiss watchmakers and in the late 1920's he went to Philadelphia and apprenticed with an uncle to learn how to repair watches & clocks. After spending time in Philadelphia & Cleveland, he returned to South Dakota where he worked as a watchmaker. While working at Landstrom's, he met Irene Neugebauer who worked at the store and they married in 1940. In 1957, they bought Schmidts Jewelry, which was destroyed by fire in 1961. After the fire, they purchased another store, Clems Jewelry, which they operated until their retirement in 1976. Clem & Irene were active volunteers delivering Meals on Wheels together for many years. Clem continued doing this with other friends following Irene's death in 1987. Clem enjoyed time with family and friends. The annual family reunion at Sylvan Lake was a special joy for Clem. He loved to dance, ride horses, play cards and play pool.
