Nathan Silver, an architect whose 1967 book, Lost New York, offered a history lesson about the many buildings that were demolished before the city passed a landmarks preservation law that might have saved them, died on May 19 in London. He was 99.

Mr. Silver’s book was a photographic guide to what had vanished over many decades. “While cities must adapt if they are to remain responsive to the needs and wishes of their inhabitants, they need not change in a heedless and suicidal fashion.”

Rosalind Fox Solomon, a photographer whose black-and-white portraits shot in the American South, Israel and diverse spots around the globe earned her the admiration of critics and a place in the world’s most prestigious museums, died on June 23 in Manhattan. She was 95.

Ms. Fox Solomon came to realize that “something is different about me when I’m taking pictures,” she said. “I connect with something in myself that’s different than when I’m in social contact…I always have tried as much as possible to connect my inner feelings to my pictures.”

Ms. Fox Solomon was awarded a Guggenheim Fellowship in 1979. Her work is in the collections of the Bibliothèque Nationale de France, the Museum of Modern Art and the Metropolitan Museum of Art in New York, the Museum of Fine Arts in Boston, and the National Gallery of Art in Washington.

Daniel Abraham, an entrepreneur who turned a tiny family business into a giant that dominated the weight-loss industry with popular brands like Slim-Fast and Dexatrim, died on June 29 in Manhattan. He was 100.

Mr. Abraham built his fortune on a pharmaceutical company that his father, a dentist, bought for $5,000 in 1947 after spotting it in an advertisement in the trade publication Drug Store News. He expanded the company into an empire that included Slim-Fast.

Mr. Abraham, whose family lived in Israel for much of the 1970s, was also active politically. In pursuit of Middle East peace, he cultivated relationships with top Israeli, American and Arab leaders, including Prime Minister Ariel Sharon, a friend for more than three decades.

Forbes estimated Mr. Abraham’s wealth this year at $2.4 billion.

In a long career as a psychoanalyst, Anna Ornstein, who was deported to Auschwitz when she was 17 and experienced unspeakable horror in her youth, embraced a school of psychotherapy that stresses empathy — a belief that all people, even those who seem the most vile, contain a spark of humanity. Dr. Ornstein died on July 2 at her home in Brookline, MA. She was 98.

She and her husband, also a Holocaust survivor, emigrated to the United States in 1950. She taught child psychiatry at the University of Cincinnati, at Harvard Medical School, and at the Massachusetts Institute for Psychoanalysis. She also spoke about the Holocaust to young people and community groups.

Jack Kleinsinger, a lawyer by day who in his evening hours indulged his passion for music by creating and running Highlights in Jazz, one of New York’s longest-running concert series, for which he arranged and hosted more than 300 shows over a 50-year run. Mr. Kleinsinger died on June 11 at his home in Manhattan. He was 88.

He once said he never intended to leave a legacy. He just wanted to hear good jazz, and he befriended many of the artists me met in the city’s jazz clubs and concert halls.

Mr. Kleinsinger left no immediate survivors, nor did he leave any directions for his burial other than his wish to be cremated. A few days after his death, his cousin Elizabeth Elliot arranged for him to be interred in a mausoleum at Woodlawn Cemetery in the Bronx, where many jazz greats are buried. His remains sit in a niche just a few rows away from those of the actress and singer Diahann Carroll.

“Somewhere, Jack is smiling,” she said. “I’m sure of that.”

Mortimer Matz, a New York public relations impresario who was credited with introducing the raincoat as an essential fashion accessory so that recently arrested defendants could hide their handcuffs from photographers, and who co-founded a gluttonous annual hot dog eating contest to promote Nathans of Coney Island, died on June 26 at his home in Manhattan. He was 100.

Sometimes likened to an upscale version of the unsavory press agent Sidney Falco in the 1957 film “Sweet Smell of Success,” Mr. Matz contrived his share of audacious stunts, such as the time he bought a stone and had it inscribed with hieroglyphics by a curator at the Met. A taxi driver turned it into the police as planned, and an Egyptologist from the Brooklyn Museum pronounced it unreadable. But Mr. Matz, who was representing radio station WINS at the time, revealed that the drawings roughly translated as “Everybody’s mummy listens to WINS.”

Richard Greenberg, who won frequent praise for his sharp-witted plays about the manners and mores of urbane New Yorkers, and who received a Tony Award in 2003 for “Take Me Out,” his play about a gay baseball player, died on July 4 in Manhattan. He was 67.

Mr. Greenberg rose to theater fame in the 1980s with a string of scripts that delved into the interior lives of young urban professionals (yuppies).

In addition to the Tony Award for best play, “Take Me Out” won the same honor from the New York Drama Critics’ Circle, and was a finalist for the Pulitzer Prize. It was revived on Broadway in 2022. A prolific writer, Mr. Greenberg wrote more than 30 produced plays, including original works, adaptations and one-acts, as well as an occasional television script.
