Lawrence D. Downing is a Minnesota lawyer who, from 1983 to 1996, served nine years on the Sierra Club board of directors, including as Club president from 1986 to 1988. From 1986 to 1995, he was a Sierra Club Foundation Trustee, including as president from 1990 to 1992. Downing was born in August 1936, in McPherson, Kansas. In 1958, he earned his Bachelor of Science in Chemistry from Iowa State University, and then worked for the Proctor & Gamble Company in Cincinnati, Ohio, where he helped invent the liquid cleaner "Mr. Clean." He earned his Juris Doctor in 1962 from the University of Minnesota Law School, where he edited the Minnesota Law Review. From 1962 until his retirement in 2010, Downing practiced matrimonial law in Rochester, Minnesota. After joining the Sierra Club by mail in 1969, Downing held leadership positions at every level: as founder and chair of his local Wasioja Group in the North Star Chapter; as chair of the North Star Chapter; as an executive in the National Sierra Club Council; as chair of numerous national committees; as a Sierra Club Foundation Trustee, including a term as president; and as an elected member to the national Sierra Club board of directors for nine years between 1983 and 1996, including his terms as Club president from 1986 to 1988. As a national leader, Downing earned the nickname "Mr. Grassroots" for advocating training and support for Sierra Club volunteers. Downing also forged international connections with the John Muir Trust and the Royal Scottish Geographical Society to help return to Scotland the preservationist legacy of Sierra Club founder John Muir, who was born in Scotland. Downing received the Centennial Campaign Award for his work in the late 1980s and early 1990s as Chair of the Planning Committee for the Sierra Club's $110 million Centennial Capital Campaign. He also received the Sierra Club's award for continued service by a past director of the Club. In 2003 and 2004, Downing played a fundamental role in the "Groundswell Sierrans" movement to prevent an elected take-over of the Sierra Club board of directors by a coalition of immigration opponents, white supremacists, and animal rights organizations who disguised their campaign in rhetoric against overpopulation. Downing also served on the board of the Minnesota Center for Environmental Advocacy, the largest non-profit environmental law firm in Minnesota. In this interview, Downing details all of the above and comments on the evolution of both volunteer and staff leadership of the Sierra Club, including several conflicts within and between volunteer and staff leadership.
