Loraine P. Bernstein, a musical trust's administrator who assisted young musicians in gaining an audience, died of a heart attack Sept. 20. The Mount Washington resident was 82. Mrs. Bernstein appeared in local operas and cultivated friends who shared her enthusiasm for music. She often entertained at Saturday night musicales at her Milford Mill Road home, keeping a Baldwin baby grand piano and invited guests to perform between servings of wine and hors d'oeuvres. Mrs. Bernstein was a friend of Yale and Peggy Gordon, who established a trust fund for local music performances and young musicians. After Yale Gordon's 1984 death, she was named his trust's assistant director and began assessing those recipients who would receive the fund's financial grants. "Loraine made a phenomenal impact on the cultural scene in Baltimore," said Ed Polochick, a friend who is artistic director of Concert Artists of Baltimore. "She was instrumental in maneuvering the funds to help and promote young artists in Baltimore...She was not just a talent scout and promoter. She went beyond all that in her emotional support. She was a real beacon."
