Dorothy Rose Brueggemann was born in south St. Louis County on Feb. 19, 1932, to Aloys and Rose (Scherrer) Brueggemann. After completing eighth grade, Dorothy entered the Sisters of the Most Precious Blood’s aspirancy. As an adult, she marveled that she had made this decision at the tender age of 14, and she credited God’s grace for enabling her to grow into her life choice. She was received into the novitiate on July 25, 1950, and was given the name Sister Lorraine. She professed first vows on Aug. 10, 1952.

Sister Lorraine earned a bachelor’s degree in Latin at Saint Louis University and a master’s degree in theology at St. John’s University in Collegeville, Minnesota.

She taught elementary grades in Missouri at St. Patrick in Wentzville, St. Alphonsus in Millwood, Assumption in Mattese, St. John the Baptist Gildehaus in Villa Ridge and St. Joseph in Cottleville. She served as both principal and teacher at St. Maurus in Biehle.

In 1972, Sister Lorraine was missioned to St. Elizabeth Academy where she would serve for 42 years. She taught theology and later served as admissions director and financial aid director. She worked tirelessly to assist girls who had a strong desire for education but lacked financial resources. In 2005, she was honored by the St. Louis Archdiocese with the Servant of the Poor award.

In addition to teaching at St. Elizabeth, Sister Lorraine wrote for the St. Louis Review. She addressed her weekly column, Youth Views, to young people. Then, her teaching instinct prompted her to invite students to write. She organized and edited submissions from 25 high schools throughout the archdiocese.

Sister Lorraine was preceded in death by her parents, her brother George, and his wife, Carole. She is survived by her brother Edward (Jane) Brueggemann, by her sister, Lorraine (James) Schinsky, nieces, nephews and many friends.

Burial was in the convent cemetery.
