Agnes Margarethe Olsen Larsen Kornicker was born in Hillerød, Fredriksborg, Denmark on the 19th of September 1890. Agnes was the second child of Hans Laurits Olsen and Caroline Dorthea Jensen. A boy, Hans Rudolph Olsen was born a year before Agnes.
Caroline, either widowed or divorced, married for a second time to Alfred Larsen, a violin teacher, who legally adopted both children. The family emigrated to Montreal, Canada and then again to Vermont in 1908.
Agnes attended private schools in Denmark and Montreal. In Vermont, she attended the Bishop Hopkins Hall private school at Burlington and, studying violin with her father and brother, she became an accomplished musician.
By 1920, Agnes was living with her brother in Manhattan where both were working as violinists. In 1932, she married Hartwig Kornicker, a german emigré. While the marriage lasted only a few years, Agnes would keep the name Kornicker for the rest of her life.
Alfred Larson died in 1949, Caroline Larsen in 1960, and brother, Rudloph in 1977.
Agnes Kornicker died at Doctor's Hospital in Manhattan on the 26th of March 1989 and was buried on Hart Island on the 23rd of May 1989.
