Heather Menzies-Urich, a TV and movie actress whose best-known role was Louisa von Trapp in the 1965 movie The Sound of Music, died Sunday night in Frankford, Ontario, in her native Canada, her son Ryan Urich said Monday. She was 68 and had recently been diagnosed with terminal brain cancer. Menzies-Urich landed the role of the third-oldest von Trapp child at age 14, and she went on to act in the movies Hawaii, Piranha, and The Computer Wore Tennis Shoes, as well as the TV shows Dragnet, Bonanza, The Bob Newhart Show, and a starring role in Logan's Run.
Menzies-Urich, whose family moved from Canada to California when she was a teenager, met her husband, Robert Urich, while filming a commercial for Libby's Corned Beef Hash in the mid-1970s, Variety reports. After he died from cancer in 2002, Menzies-Urich started the Robert Urich Foundation for cancer research and support. She is survived by three children, several grandchildren, and one great-grandchild.
