“ALL KNOWLEDGE IS USELESS UNLESS MANIFESTED IN DEEDS”
SIR JOHN MURRAY (1841-1914) SIGNED QUOTE, “John Murray”, on a card 5 x 3, by the pioneering Scots-Canadian oceanographer, marine biologist, limnologist, and considered to be the father of modern oceanography. He participated in the Challenger Expedition of 1872-76, the scientific program that made many discoveries to lay the foundation of oceanography. And, he later published The Report on the Scientific Results of the Voyage of HMS Challenger, a work of more than 50 volumes of reports. Murray would later begin surveying the fresh water lochs of Scotland, which resulted in the six volume Bathymetrical Survey of the Fresh-Water Lochs of Scotland (1910). In April 1910 Murray led a four-month expedition on an oceanographic survey of the North Atlantic to take physical and biological observations at all depths between Europe and North America. Their published findings The Depths of the Ocean (1912) became a classic for marine naturalists and oceanographers. He was the first to note the existence of the Mid-Atlantic Ridge and of oceanic trenches. His handwritten quote, in full: “All knowledge is useless unless manifested in deeds.” In fine condition, with minor age toning.
