The portrait above is of J. Robert Kelley and Albert Koett. Two pioneers of X-ray technology, based right here in Covington Kentucky.

“In 1915, J. Robert Kelly, a native of Virginia, a great promoter and booster,4 proclaimed that the largest manufacturer of X-Ray apparatus in the world would soon double its workforce of 50 in its new factory building on West 4th Street ,where visitors soon could see X-ray products already “used exclusively” by the “great Mayo Clinic” and others.5 Kelley had established a partnership: Kelley-Koett would sell at cost to Mayo in return for using Mayo’s specifications in its products without paying royalties.”
