From page 282...
... JOHNSON HAROLD GENE SOWMAN, a remarkably productive engineer at the forefront of the changing field of post–World War II ceramic science and technology, died on November 29, 2012, at age 89. He was a pioneer in ceramic materials for nuclear reactors in his early career and later developed sol ceramics technology into new processes for manufacturing ceramic materials and products.
From page 283...
... At 3M he was coinventor of a number of nuclear materials patents that formed the basis of microspherical coated fuel particles embedded in graphite fuel elements such as the ensuing pebble bed reactors. These particles were first used in a prototype reactor designed for space rocketry, the Kiwi B4-E 301, successfully tested by Los Alamos National Laboratory in the Nevada desert.
From page 284...
... He was proud of his home state and a generous contributor to the University of Illinois, from which he obtained his undergraduate and graduate degrees. His service outside his local community included two years as industrial advisor for the Department of Engineering at Tuskegee University, membership on the NAE Steering Committee on the Commercialization of Technology and the Materials Advisory Board, and numerous activities for the University of Illinois Ceramic Engineering Department.
