Addison Clark's work and influence was like the silent but incomputible [sic] forces of nature, great without ostentation. If modesty, and that self depreciation that is the extreme manifestation of it, were ever a fault in any one they were in him. He seemed never to suspect the greatness of personality in himself, that his friends and intimates plainly saw in him. When told of such estimates of him by those friends he looked incredulous and treated them as the exaggerated expressions of personal law and interest. In all the planning of his great life work, and in his public addresses which were many and important, self was never seen.
