Dr. Walter J. Clore (July 1, 1911 – February 3, 2003) was a pioneer in wine growing and agricultural research in Washington State and has been formally recognized by the Washington State Legislature as the "Father of Washington Wine". Among his contributions to wine growing in Washington state was his extensive research into what areas of the state that premium wine grapes (particularly Vitis vinifera) would most thrive in.
Born in Tecumseh, Oklahoma, Clore studied botany and agriculture in high school in Tulsa before attending Oklahoma Agricultural and Mechanical College (Today known as Oklahoma State University). While majoring in horticulture, Walter Clore also lettered in football as a lineman and was president of the agricultural fraternity Alpha Gamma Rho and elected to honorary membership to another agricultural fraternity Alpha Zeta. In the summers, he did survey work in Ohio and Indiana for the United States Department of Agriculture.
Research and work
In 1934, Walter Clore married Irene Welsh and accepted a horticultural fellowship at Washington State College (now Washington State University) in Pullman, Washington. One of his first studies there was to measure the effect of "Bordeaux Sprays" (a sulfur and lime based mixture) on the photosynthesis of red and golden delicious apples. In 1937, Clore became assistant horticulturist at the Irrigation Branch Experiment Station (now known as the Irrigated Agriculture Research and Extension Center) in Prosser. There he oversaw the experimental plantings of nearly 20 Vitis labrusca hybrids and 7 Vitis vinifera grape varieties. In the years that follow, under Clore's direction the plantings at the Experiment Station would expand to include 45 hybrids, 71 Vitis vinifera, and 10 interspecies Vitis hybrid rootstock. By 1974, Clore had overseen the plantings of 312 grape varieties.
His work laid the foundation for the rebirth of the Washington State Wine industry as it conclusively proved that premium quality vinifera wine grapes could be grown in the rich volcanic soil and warm climate of the Columbia River Valley. His test of trellis designs helped to promote the widespread adoption of modern mechanical harvesting techniques.
