In 1964/65 Earl was chosen for a postdoctoral fellowship to the University of Gronigen in The Netherlands. He provided for his family an unforgettable experience of living in the land of their heritage.
Earl said that he chose chemistry because it was hard and he saw great things starting to happen in the field. What he loved was history. He was able to meld that love of history with his faith by teaching Sunday School at the First Presbyterian Church and at the Presbyterian Manor. He taught the high school Sunday School and continued on to teach Bible History and Archeology in the Chapel at FPC for over 50 years. He loved putting together power point presentations using scriptures, maps and famous artwork to enhance the lessons. He continued creating power points till his death with the help of his daughter, Gretchen.
Earl had a great sense of humor and was known for always having a joke or story to tell. He enjoyed sailing, studying history and the Bible. He had a great love of classical music and grand master paintings.
