From the Morgan Sweeney Photograph Collection (PH-00228). Harvey W. Boyce, Boulder Canyon Project Electrician, became the first Bureau of Reclamation apprenticeship graduate in the Nation on April 16, 1951, when he was presented his "diploma" in a brief ceremony at Hoover Dam. Doing the horrors is John H.Phillips, armature-winder at Hoover Dam and member of the apprenticeship committee. A few moments later Mr. Boyce was handed his promotion from apprentice to journeyman by Director of Power L.R. Douglass, third from left. The Boulder Canyon Project was the first throughout the Bureau of Reclamation to establish the apprenticeship training program. Left to right are Morgan J. Sweeney, Construction and Maintenance Superintendent, Boulder Canyon Project; Steve Wenta, cabinet maker and finish carpenter and member of the apprenticeship committee; Mr. Douglass, Mr. Boyce, Mr. Phillips, M.H.Mitchell, Regional Personnel Officer and chairman of the apprenticeship committee, and Lloyd Hudlow, Assistant Director of Power.
