In Memoriam

March 25, 2020 – Father David L. Koesterer, SJ, died March 11, 2020 in St. Louis. He was 90 years old, a Jesuit for 68 years and a priest for 55 years.

Father Koesterer donated his body to science. There will be a memorial Mass at a later date when public events are again allowed.

He was born in Freeburg, Ill., on May 11, 1929, one of eight children of Albert J. and Katherine E. Koesterer. In addition to his parents, he was preceded in death by brothers Albert, Larry, Hank and Ralph, and by his sisters Cleo Boze and Esther Webb. He is survived by his brother Herman (Maureen) Koesterer, of Belleville, Ill., and a sister-in-law, Julie Koesterer, of Bridgeton, Mo.

He entered the Society of Jesus (the Jesuits) Aug. 8, 1951 at St. Stanislaus Seminary in Florissant. He pronounced First Vows Aug. 15, 1953 and was ordained a priest June 16, 1964 at St. Mary’s College in St. Marys, Kansas. He pronounced Final Vows Feb. 1, 1972, at De Smet Jesuit High School in St. Louis.

Father Koesterer taught German and English at St. Louis University High School for two years, 1959-61. In 1967, he was assigned to teach German and French at De Smet Jesuit, where he remained for nine years. In 1976, he felt called to shift his apostolic work and dedicated the next four years to studying music; he received a master’s degree in piano from Ball State University in 1979.

Between 1980 and 1989, he served in a variety of parishes in Oklahoma, Colorado and Missouri. He served as a retreat director and spiritual director at White House Retreat in St. Louis from 1991 to 2006. He served in pastoral ministry in St. Louis from 2006 until early 2019, when health issues compelled his move to the infirmary at Jesuit Hall.

Father Koesterer earned a Bachelor of Arts in philosophy and a master’s degree in German at Saint Louis University. He studied theology at St. Mary’s College in Kansas.

We remember with gratitude all that God has done through Fr. Koesterer’s life of service to God and God’s people.
