Biographical Notes

In 1947, a 12-year-old William Turnbull flew with his parents and brother from Bermuda to New York, NY, aboard Pan American Airlines on 03/29/1947.(See, Source Citation Year: 1947; Arrival: New York, New York; Microfilm Serial: T715, 1897-1957; Microfilm Roll: Roll 7313; Line: 3; Page Number: 144, accessed 12/06/2018.)

Two years later, William accompanied his parents to Liverpool, England aboard the Cunard liner H.M.S. Brittanic from New York. They arrived in Liverpool on 06/24/1949. Their London destination was Windsor House on Victoria Street. (See, Source Citation The National Archives of the UK; Kew, Surrey, England; Board of Trade: Commercial and Statistical Department and successors: Inwards Passenger Lists.; Class: BT26; Piece: 1246, accessed 12/06/2018.)

During the 1980s, Turnbull and a partner started a vineyard in Sonoma, CA. The University of California, Berkeley, College of Environmental Design Archives archivists, Betsy Frederick-Rothwell and Laura Tatum, said of this part of Turnbull's life: "In the early 1970s, Turnbull and his friend (and lawyer, and client) Reverdy Johnson went into business together growing grapes in an esteemed region of the Napa Valley. When, one year, the winery to which they usually supplied their grapes declined to purchase them, Turnbull and Johnson invested in winemaking equipment and began (with the expert assistance of oenologist Kristin Belair) to produce their own award-winning Cabernet Sauvignon and Chardonnay throughout the 1970s and 1980s under the name Johnson Turnbull Vineyards. Turnbull designed all of the facilities for the winery, as well as for their neighbors, fellow winemakers Jack and Dolores Cakebread. Johnson and Turnbull remained active in the Napa Valley winemaking community until the vineyards were sold in the mid-1980s."
