[35] "Judge Harry A Hollzer is today considered the most lovable personality among the Jews on the Pacific Coast....That he will be re-elected to the bench in the August primaries is the wish of all citizens and elements in the community.

His courtroom was maintained in an atmosphere of quiet dignity....Judge Hollzer was an extremely hard worker, and many weekends and holidays found him in his chambers.

His memory will remain fresh so long as there are men and women who love their fellow beings, who understand and appreciate the beauties, the privileges and responsibilities of Judaism, who know the blessing of giving and the exaltation of service.
