Walter Max Kruse of Wilmington, Delaware passed away on February 22, 2017. He was 88 years old. Walter was a highly accomplished chemist, a beloved husband, a dear father and father-in-law, and most recently known as the most adored grandfather whom we all called “Opa.”

Born in Heide-Holstein, Germany, Walter was the son of the late Walter and Martha Fehrs Kruse. He graduated from the University of Cologne (Köln) with a PhD in Inorganic Chemistry. He then completed postdoctoral studies at the University of Chicago, and also at the Max Planck Institute for Biophysical Chemistry in Göttingen. In 1964 he started working for Hercules Inc. in Wilmington as a Research Chemist, and eventually moved to ICI Americas, also in Delaware, from where he retired in 1991. He is credited with 30 scientific publications and 30 chemical patents.

Walter was always a very active member in his local community and many of his efforts focused on education. He taught Inorganic Chemistry in German at the University of Delaware as part of their Honors Program. He continued to participate in education classes, both as instructor and student, at the Academy of Lifelong Learning Institute at the University of Delaware. Walter had a great sense of humor, and appreciated literature. He worked to establish a museum in his home town of Heide-Holstein to honor the local author and cartoonist, Rudolph Dirks, the creator of the “Katzenjammer Kids.” Walter was also an active member of the Occidentals Club, the American Chemical Society, American/Schleswig-Holstein Heritage Foundation, and the Bellevue Tennis Center.

Walter is survived by his wife of 17 years, Veronika S. Kruse, and their extended family: three children from Walter’s first marriage to Edith Blackbird Kruse, who passed away in 1998: Rebecca Rugo (Barry), Elke Chenevey (James), and Lakota Kruse (Monica) and their children Sophia and Matthew Rugo, JP, Michael, and Elise Chenevey, and Annika and Elisa Kruse. He is also survived by Veronika’s son Paul (Bonnie), and their children Matthew and Jonathan Foldi; and by Walter’s sister Ellen Kruse.
