Christina Schnitzer was born at Watson, Missouri on Nov. 24, 1862, Both parents were from Bavaria, Germany. She entered at Clyde on Sept. 23, 1891 and received the Benedictine habit on March 17, 1892. She was professed as Sister M. Monica on Nov. 17, 1893 and made her perpetual vows on July 12, 1900. She had the joy of celebrating her Golden Jubilee in 1943 and of receiving the Consecration of Virgins in 1952, just a few months before her death.

Sister was a small, frail person, wiry and energetic, always cheerful, with a gentle sense of humor. Though not a trained nurse, she was well-versed in medicine and for some years was Sister M. Euphemia's helper in the infirmary. Later she assumed charge, and is remembered for her motherly kindness and sympathy, which in itself made the sick feel better (so they said).

From September 1917 till March 1928, Sister was at the convent in Chewelah. She also spent some years at Mundelein during the early years of its foundation. Though in poor health for many years, Sister never complained. Confined to the Clyde infirmary in her declining years, she prayed much and was always ready to help others. Sometimes, when asked how she was feeling, she would answer with a wry smile, "Pretty worse."

Sister died on May 6, 1953 at the age of ninety- one. She was just a few months short of celebration of her Diamond Jubilee.
