Martin C. Dreiwitz, who drew on his twin passions for travel and classical music to found the Long Island Youth Orchestra, died on June 20 at a hospital near his home in Oyster Bay, NY. He was 91.

The orchestra had about 100 performers, all recruited by Mr. Dreiwitz, who also raised the funds and conducted every performance from the orchestra’s founding in 1962 to his retirement in 2012. In addition to playing four concerts as year locally, he took the group on summer tours with stops in Greece, Kenya, the Seychelles, India, Sri Lanka and Israel.

Thanks to Mr. Dreiwitz’s guidance, the orchestra’s 4,000- (and counting) alumni have gone on to play in many of the country’s major symphony orchestras and chamber groups. In 2018, hundreds of alumni returned for a concert in his honor, and he even mounted the podium to conduct a selection from his beloved “Porgy and Bess.”

Larry Storch, who played a memorable television oddball on the 1960s sitcom “F Troop,” died July 8 at his home on the Upper West Side of Manhattan. He was 99.

Mr. Storch had a long career as a nightclub comic and as a character actor on the stage and on big and small screens, but that work was dwarfed by the impression he made during the two-season run of

“F Troop” on ABC from 1965 to 1967. The show was a slapstick comedy about an outpost called Fort Courage in Indian country just after the Civil War. He and his misfit pals were constantly hatching moneymaking schemes involving the local Indian tribe, the Hekawis.

Jerome Eisenberg, a leading New York antiquities dealer who guarded against the illegal importation and sale of ancient art, died on July 6, his 92nd birthday, in Manhattan.

Mr. Eisenberg started a mail order ancient coin business with his father when he was 12, and over the years sold an estimated 40,000 ancient artifacts and appraised countless others for prospective buyers and insurance adjusters. He also testified as an expert witness on the value and source of antiquities.

Often described in the press as the “dean of New York antiquities dealers,” Mr. Eisenberg founded the Royal-Athena Galleries in Manhattan in 1954, specializing in Classical Greek, Roman and Egyptian art. In 1970, he established Collector’s Cabinet, a natural history gallery featuring minerals, seashells, fossils and butterflies. He later expanded Royal-Athena, opening branches in Beverly Hills and London. He retired in 2020 and closed his galleries.

René Slotkin, one of the last of the “Mengele twins,” died July 10, in New York. He was 84. Born René Guttman in 1937 in Teplice-Sanov, Czechoslovakia, he was 3 years old when he and his twin sister, Irene, were deported to Theresienstadt with their mother, Ita. Two years later, they were moved to Auschwitz, where their mother and father were killed, and the twins separated and subjected to medical abuse by Josef Mengele, the infamous Nazi physician.

After the camps were liberated, René was repatriated to Czechoslovakia and lived with families there. Irene, who had been placed with a Christian family, was found by the Joint Distribution Committee, who wanted to return her to a Jewish family. She was taken to New York by Rescue Children Inc., and adopted by the Slotkin family on Long Island. Irene told her adoptive family that she had a twin brother. The Slotkins hired a private investigator who found René in Europe, and the Slotkins adopted him, too. He was 12, and had not seen his sister in six years.

According to The Times of Israel, René went to college, served in the U.S. military, married and had four children. It took four decades before René and Irene could speak openly about their experiences during the Holocaust. In his later years, René volunteered at Camp Sharon in Tannersville, NY, where he taught woodworking and sports, and where he taught children about the Holocaust and what it meant to have survived. Irene’s story is told in a 2005 documentary, “René and I.” Irene died in 2019.

Dr. Joyce C. Lashof, who fought for health equity and broke barriers as the first woman to head a state public health department and the first to serve as dean of the School of Public Health at the University of California, Berkeley, died on June 4 at an assisted living community in Berkeley. She was 96.

In the 1960s, Dr. Lashof founded a community health center to provide medical care in a low-income section of Chicago. After her appointment as director of the Illinois Department of Public Health in 1973, the year of the Supreme Court’s Roe v. Wade decision codifying the constitutional right to abortion,  Dr. Lashof established protocols to provide women access to safe abortion in the state. She also fought discrimination against people with AIDS and protested Apartheid in South Africa.

She championed social justice outside of her professional life as well, taking her family on so many marches for peace and civil rights in the 1960s that they came to view mass protests as “a family outing,” her son, Dan, said.

Toward the end of her life, Dr. Lashof was heartened by the many advances in social justice that had been made over the years. But in recent months, she was aghast to hear that the Supreme Court was considering overturning Roe v. Wade.

Harvey Dinnerstein, who in addition to his paintings and drawings was also a longtime art teacher, died on June 21 in Brooklyn. He was 94.

Mr. Dinnerstein came of age in the early 1950s. Unmoved by Abstract Expressionism, he followed in the artistic tradition of realists, depicting the life around him: on the subway, in parks, outside brownstones like his own in Brooklyn.

Mr. Dinnerstein taught for 40 years at the Art Students League. He also taught at the School of Visual Arts and the National Academy of Design.
