Robert Woolston Hunt (1838-1923) was a metallurgical engineer, inventor, and superintendent in the American steel industry. He was elected President of the American Institute of Mining Engineers as well as the American Society of Mechanical Engineers, which shows the high esteem in which his peers held him. During the Civil War he served as commander of Camp Harrisburg in Pennslvania and as a mustering officer for the state of Pennsylvania, undoubtedly putting his administrative talents to good use.
The piece in fine silver that is depicted was awarded to Edwin Chester Wright for a paper titled "The Manufacture and Properties of Killed Bessemer Steel." By 1945 the medal had only been awarded nine times, so this is probably a very rare medal.
The rectangular plaquette measures 100.9mm x 69.3mm and was struck in silver-plated bronze or fine silver by the Medallic Art Company of New York. No mintage is reported. I assume that it was also struck in bronze but I have not encountered that variant yet.
