memorial tree (Halbo-12)

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

Note: As part of the SLAC Science and User Support Building (SUSB) construction project (2013-2015), several of the SLAC memorial and tribute trees are being relocated and replaced. Once the SUSB construction has been completed, this page and the accompanying map will be updated to show the trees' new locations.
