Henry Story McKown (Hank) of Oak Ridge at the age 94 died Saturday, August 29, 2015.

Hank McKown was born April 12, 1921 in Rochester, NY,son of Samuel Campbell McKown and Louise Story McKown. As a teenager, he spent many years helping his father run and repair a small flour mill outside the city of Rochester. They also built a sailboat and enjoyed many summer days sailing, canoeing and swimming in the Adirondacks. During the winter, the family spent many hours snow skiing and ice skating. After college he helped his father build a lake cabin on Canandaigua Lake near Rochester, which was later the model for a lake cabin on Watts Bar Lake that he built for his family .

After graduating from a public high school, he went to Williams College, Williamstown Massachusetts majoring in chemistry with a minor in physics and an interest in electronics and graduating in 1943 .

In December 1942 he started working in the chemistry department of Columbia University on a secret project which later was called the Manhattan Project. After eight months he was sent to Trail, British Columbia to help in the development of an analytical laboratory that was measuring the concentration of deuterium in heavy water. The experience in Canada was very enjoyable being in a small town and a country outside the US to explore, hike and ski. After 14 months he returned to Columbia University where all activities there were involved with research for the K-25 uranium enrichment facilities in Oak Ridge,TN.

After the end of World War II, the laboratory in New York was shut down and Hank transferred to K-25 in Oak Ridge in 1946. In 1960 he transferred to Oak Ridge National Laboratory where he worked until retirement in 1993. He then did consulting work three days a week for 17 more years until he turned
88. All his work involved the improvement of the instrumentation in mass spectrometers for the measurement of isotopic ratios.

In 1946 Hank met Helen Howes in Oak Ridge square dancing at Glenwood Elementary School and married her a year later. They enjoyed a strong, loving marriage. They spent many a summer taking their four daughters to see many US states and enjoying the national parks when they weren't at their lake cabin.

In 1975 his work took them to Vienna, Austria for three years where he worked for the International Atomic Energy Agency in the Safeguards project. It was one of many highlights in his professional career. This was a wonderful experience for Hank and Helen as they met people with whom they still correspond in Europe. They enjoyed many a symphony and opera in Vienna, skiing and hiking in the Alps and touring throughout Europe, the Middle East, the Eastern Bloc countries and Russia during those three years. After coming back to the States, later they traveled to China, Australia , New Zealand, Kenya, Tanzania, Belize, Costa Rico, Peru and the Galapagos Island, as well as Hawaii and Alaska .

In 1949 Hank was one of the founding members of the Oak Ridge Unitarian Church and extremely active serving on the building,finance and other committees . He also was a member of the Instrument Society of America and the Greenways Committee for the City of Oak Ridge. After retirement, Hank volunteered at the American Museum of Science & Energy for at least 10 years where he had the opportunity to share his experiences and knowledge of the history of Oak Ridge with visitors. His only lunch box that he took to work for all those years now rests in the flat top's kitchen at the museum.

Mr. McKown is survived by his loving wife of 68 years, Helen Howes McKown; daughters, Louise McKown of Oak Ridge; Elizabeth (Betsy) and husband Dexter Perkins of Grand Forks, ND; Anne and husband Garry Child of Dripping Springs, TX; Jean and husband Ronald Norton of Solebury, PA; four grandchildren, George and Douglas Perkins and Eric and Lindsey Norton, and one great granddaughter, Cora Perkins.
