This noted farmer, inventor, and entrepreneur played a key role in demonstrating the agricultural potential of the drought-prone Palliser Triangle. During the Great Depression, Noble worked closely with the Dominion Experimental Farm to promote the latest dry-land farming techniques. In 1936 he invented the Noble Blade, a cultivator that cut weeds off at the roots without disturbing the soil surface, significantly reducing erosion. Noble's implement company became the largest of its kind in Alberta, and produced much of the specialized machinery for dry- land farming in the second half of the 20th century.
