Stanley Manahan

A celebration of life for Peabody High School alumnus Stanley Eugene Manahan, 85, who passed away Jan. 29, 2023, in Columbia, Missouri, will be 1 p.m. Sunday, June 11, 2023, at Stoney Creek Hotel, 2601 S Providence Rd., Columbia, Missouri.

Private interment will take place at Prairie Lawn Cemetery in Peabody.

He was born on September 5, 1937 in Hillsboro to Lawrence Manahan and Ethel (Blackmur) Manahan. He was united in marriage to Anne Fisher on March 29, 1969, at Sacred Heart Catholic Church in Columbia.

After surviving a life-threatening bout of rheumatic fever that necessitated his being homeschooled for two years during childhood, Stanley regained his health and graduated from Peabody High School in 1956.

He earned an AB in chemistry at what is now Emporia State University in 1960 and a PhD in analytical chemistry in 1965 at the University of Kansas.

Stanley then joined the Department of Chemistry at the University of Missouri-Columbia, where he served as thesis advisor for 30 PhD and 15 master’s candidates and taught until his retirement as a full professor in 2002.

Since 1968, his primary research and professional activities, in which he was considered a pioneer, were in environmental chemistry, with more recent emphasis on hazardous waste treatment.

He was the author of approximately 100 research papers and 18 chemistry textbooks, the most well-known being “Environmental Chemistry.”

He taught courses on environmental chemistry, hazardous wastes, toxicological chemistry, and analytical chemistry and lectured on these topics throughout the United States as an American Chemical Society local sections tour speaker and in a number of countries, including France, Italy, Austria, Japan, Mexico, and Venezuela.

Stanley also spent many summers researching and teaching in Wyoming and Michigan.

In addition to his numerous textbooks, Stanley also authored a humorous book about his life in Kansas, “Lat Me Thank.”

Stanley made frequent visits to his beloved Kansas and to Estes Park, Colorado, where he felt a spiritual connection with nature.

He enjoyed hiking in the Rockies and, later in life, riding his recumbent bicycle, delighting in the occasional wildlife sighting.

Always a friend to animals, he also loved his dogs, Towser, Fritz, and Bunny.

Stanley is survived by his wife, Anne; daughters Valerie Manahan (and partner Chadwick J. Smith) of Los Alamitos, California, and Veronica Manahan (and partner Carlos Alvarado) of Phoenix; brother Robert Manahan of Huntington Beach, California; sister Lenora Manahan (and partner Kaye Johnson) of Oklahoma City; and grandchildren Destry, Madeleine, and Cormac, whom he adored.

Memorial contributions can be made in Stanley’s name to Stanley E. Manahan Science Scholarship, Peabody High School Alumni Endowment Association, c/o Emma Pease, Vintage Bank, 201 N Walnut St, Peabody KS 66866.

Arrangements are under the direction of Parker-Millard Funeral Service and Crematory, 12 E. Ash St., Columbia, (573) 449-4153. Condolences may be left for the family online at
