Dr. Judith L. Rapoport, a child psychiatrist who brought public awareness to obsessive-compulsive disorder, died on March 7 in Washington D.C. She was 92.

            The disorder had long remained in the shadows because of the shame that surrounded its symptoms, which could include habits like checking and rechecking that appliances were off, performing counting rituals before doing something as simple as walking through a doorway, or scrubbing hands with soap and water until the skin was raw. Dr. Rapoport showed a neurological basis for repetitive thoughts, and also for their linked compulsions or pointless rituals of behavior.

            In addition to research on obsessive-compulsive disorder, Dr. Rapoport oversaw influential studies that shed light on attention deficit hyper activity disorder and childhood-onset schizophrenia.

Pedro Friedeberg, a Mexican Jewish artist who was often called “The last Surrealist,” known for his hallucinatory paintings of imaginary cities and for his absurdist furniture designs died on March 5 in San Miguel de Allende, Mexico. He was 90. Born in Italy to German Jewish parents, Mr. Friedeberg moved to Mexico with his family as a child and was later hailed as an artistic force in his adopted country. He worked in various mediums, including sculpture and printmaking, but found fame with paintings and drawings that transcended the boundaries of his university architecture studies. His paintings and lithographs were intricately geometric and dreamlike, conjuring otherworldly skylines, town centers, buildings and temple-like interiors.

                     For all his other accomplishments, Mr. Friedeberg is best remembered for his hand chairs. More than 5,000 have been produced in a variety of materials, some fetching tens of thousands of dollars at auction.

Nathan Farb, a photographer whose career took him from downtown Manhattan to a city in Siberia and then to the Adirondack Mountains of New York, died on March 26 at his home in Jay, a town in Adirondack Park. He was 85.

            Mr. Farb did not pick up a camera in a serious way until he was 25, but when he did, he felt an immediate desire to be a photographer.

            “The camera satisfied so many needs for me: The need to be with people, the need to connect to people, the need to express myself, the need to be able to comment on society,” he said.

Sid Krofft, who with his brother Marty made zany children’s programming, gaining a following among both the young and adult members of the counterculture, died on April 10 in Los Angeles. He was 96.

            According to The New York Times, Mr. Krofft was “an eccentric visionary, a kids’ show P.T. Barnum who created improbable programming with a combination of creativity and chutzpah.” What tied the shows together was a madcap feel of fantastical creatures, elaborate costumes and puppets, psychedelic sets and slapstick humor — “ a mélange of the Three Stooges and “Alice in Wonderland,” The Times said.

            He was proud of many of his shows, Mr. Krofft had said, especially “Pufnstuf,” but watching reruns of the worst Krofft programs could make him cringe. “I have to turn away once in a while,” he said, “because I think, ‘Oh, my God, how did I ever allow that?’”

Adriano Goldschmied, the Italian businessman known as “the godfather of denim” for his role in developing versions of the world’s most popular fabric, died on April 5 in Castelfranco Veneto, a town near his home in Asolo, Italy. He was 82.

            On any given day, marketers say, nearly half the world’s population is wearing jeans. Last year, more than $98 billion worth of jeans were sold worldwide, and if you wear jeans, you own a pair that is influenced in some way by Mr. Goldschmied’s presence in the industry.

            By his count, Mr. Goldschmied collaborated on or started more than 50 brands, including Gap 1969, a retro label named for the year Gap was founded, as well as Goldsign and AG Adriano Goldschmied, now known as AG Jeans.

Iris Cantor, an arts patron and philanthropist who with her investment banker husband, B. Gerald Cantor, the founder of Cantor Fitzgerald, amassed — and then bestowed to various museums — one of the largest private collections of Rodin sculptures in the world, died on Feb. 22 at her home in Palm Beach FL. She was 95.

The Iris & B. Gerald Cantor Foundation’s major beneficiaries include the Brooklyn Museum, the Metropolitan Museum of Art, the Los Angeles County Museum of Art, Stanford University, the Musée Rodin in Paris, the College of the Holy Cross in Worcester, MA, and the North Carolina Museum of Art in Raleigh. She also funded health centers in major hospitals across the country.

In an interview with the Metropolitan Museum in 2022, Mrs. Cantor said, “Art should contribute in a meaningful way to the life of a community and to our collective understanding of who we are, where we came from, and even where we might be headed. There is still no better place for all of this to happen than at museums, which preserve and showcase the results of human creativity.”
