Throughout its history, the staff, faculty and site office personnel at the SLAC National Accelerator Laboratory have chosen to honor co-workers with a variety of lasting tributes and memorials. In some instances, former staff or their families have presented one of these landscaping tributes to SLAC. (See: SLAC Trees Tell Stories, Nina Stolar, The Interaction Point (TIP) April 1997, p.9.) The list below provides the names of those who have given or received tributes or memorials, and the accompanying pdf map shows the tribute or memorial locations on the SLAC site.

The SLAC Archives, History & Records Office is indebted to Finn Halbo, who compiled all of the information on memorials and tributes made from 1962 through 2000.
