John M. Greig, 83, of Estherville, Iowa, died Saturday, Feb. 24, 2018 at the Mayo Clinic Hospital Methodist Campus in Rochester, Minn. A Carnegie hero, on Jan. 26, 1966, Greig attempted to save a well driller, 45, who had entered a 7-foot-deep well in Estherville to save another man who had passed out from a lack of oxygen inside. The well driller lifted the first man to the top of ladder where Greig and others removed him from the well, but then lost consciousness and fell from the ladder. Greig took a deep breath and descended into the well to loop a rope around the man’s leg and then exited the well, while coughing on fumes. Using a tractor, the men hoisted the well driller from the well, but he had died. Greig was born in 1934 in Estherville, earning a bachelor’s degree from the University of Minnesota in 1956 and a master’s degree in agriculture from Iowa State College University in 1960. He married Connie Kint in 1958, and served in the U.S. Army and in the Iowa state legislature. He founded North Star Bank in Estherville, and was a member of the founding board of the Iowa Cattlemen’s Association, later being inducted into the Cattlemen’s Hall of Fame. He is survived by his wife, two sons, and four grandchildren.
