William H. Ukers

William Harrison Ukers (1873–1945) was an American trade journalist and the leading historian of coffee and tea. Born in Philadelphia, he edited the Spice Mill before founding the Tea and Coffee Trade Journal in New York in 1901, which he ran for the rest of his life. His All About Coffee (1922), the fruit of seventeen years of research and travel to the producing countries, covers the history, botany, chemistry, trade, preparation and literature of the drink in nearly eight hundred pages; All About Tea followed in 1935 in two volumes. He also wrote The Romance of Coffee and The Romance of Tea for general readers.
