Obituary for Jack Bergmann

Dr. John “Jack” Gregory Bergmann, age 89, a longtime resident of Naperville, IL, passed away on April 28, 2019 at Edward Hospital.

He was born February 24, 1930 in Bark River, MI. Jack is survived by his beloved wife Janeace Harms, whom he married in 1959; loving children Jim (Linda) Bergmann, Tom Bergmann, and Mark (Cathy) Bergmann; treasured grandchildren Jon, Lisa (who preceded him in death April 24, 2019), Maryann, Isabel, Abigail, Jack, and Gus; four great grandchildren; numerous cousins, nieces, nephews, and in-laws.

Jack started his educational journey in a three-room school in Bark River, MI. At the age of 16 he graduated from High School in Escanaba, MI. He received the highest scholarship from the University of Michigan where he earned his Bachelor’s of Science in Inorganic Chemistry with high honors. He was a member of Phi Beta Kappa, Sigma Xi, Phi Lambda Upsilon, Phi Kappa Phi, and Alpha Chi Sigma all by the age of 20 in 1950. By the age of 24, Jack obtained his PhD from Northwestern University, graduating with distinction and honors, in Inorganic Chemistry.

He spent his entire working career of 33 years at Standard Oil. He became the leading expert in gel permeation chromatography at one time.

Jack enjoyed gardening, running, traveling, bridge, hunting, fishing, skiing, and coordinating a neighborhood football pool for nearly 40 years, which earned him the nickname “The Commish”.

In his later years, Jack enjoyed all the various activities of his grandchildren; both in sports and the arts. Jack was loved by many and will be deeply missed.
