Magnuson Park was named after Warrren Grant “Maggie” Magnuson (1905-1989) who represented the state of Washington in the United States Senate from 1944 to 1981. In May 1977 Sand Point Park was renamed for Senator Magnuson, who helped to secure federal funding for developing the park. More info on the park’s history can be found at: http://www.seattle.gov/parks/magnuson/
In 2011 the former Sand Point Naval Air Station was designated as a historic district by the City of Seattle’s Landmarks Preservation Board. This means that the buildings, historic monuments, sightlines, and even some landscaping and trees will be preserved in recognition of not only the naval base but the Sand Point sites’ contribution to the aviation history of Seattle: http://www.seattle.gov/neighborhoods/preservation/sandpoint.htm
Take a look at Magnuson Park’s extensive activity brochure. There is a range of activities for all ages, from indoor rainy-day fun for kids, to nature walks and even theater programs: http://www.seattle.gov/parks/magnuson/
