“Face the Nation” host Bob Schieffer headlined a tribute to late great CBS anchor Walter Cronkite on Martha’s Vineyard the other day. The event was held at Cronkite’s former home, now owned by Karen and David Brush, and the newsman’s beloved sailboat Wyntje, now owned by “Inspector Gadget” co-creator Andy Heyward, was moored just off shore. As part of the event, Cronkite’s grandson, CBS associate producer Walter Cronkite IV, presented the 2014 Cronkite Award to legendary oceanographer Sylvia Earle and Vineyard-based photographer/writer Sam Low.Names can be reached at email@example.com.
