From the many memorials written of Alfred Wolcott Gibbs by his professional associates and by the organizations of which he was a member, the following excerpts will give some sense of the deep admiration and regard he inspired:

‘‘Mr. Gibbs was endowed with a mind of fine scientific quality, which by careful training soon proved him a mechanical engineer whose opinion was eagerly sought and confidently relied upon and gave him a high position among the mechanical engineers in the railroad companies of the country. He was always an interesting and attractive companion in any group of educated men. His general information added to his scientific attainments led to prominent standing in the technical and commercial engineering societies whose work was affiliated with that of the railroad companies.” “He did valuable technical work on many committees of design, and gave time to original research, especially in metallurgy.” “Throughout all his business transactions he assumed the stern responsibility that rested upon him with that charity and sympathetic understanding which makes a business life a joy instead of mere labor or obligation.” “His was a life to emulate and an inspiration to all his friends, particularly to his younger associates in the engineering profession. The world has lost a good man and a great engineer.”

“His presence was sunlight.” “He was the most lovable of men.” “I never knew a man with a more even temperament, nor have met many who were less biased or more fair, frank, or fearless when it came to a discussion.” “He was thoughtful, considerate, and charitable. In all my association with him, I never heard him make an unkind remark about anybody. I shall miss his cheerful greetings, his quiet humor, his genial companionship, and his sincere friend¬ ship.” “I admired his high sense of honor, delightful personality, and rare, intelligent judgment.”
