Adele Faber, a former high school teacher who, with her Long Island neighbor Elaine Mazlish, wrote child-rearing blockbusters like How to Talk So Kids Will Listen & Listen So Kids Will Talk and Siblings Without Rivalry, which became bibles for generations of parents, died on April 24 in White Plains, NY. She was 96.

The parenting guides have sold more than four million copies in North America alone, and have been published in 40 countries. The impetus for the books was a lecture series by the child psychologist Haim Ginott. “I tried a few of his ideas with my own three kids and saw stunning results,” Ms. Faber said. The two women decided to write their own book based on their experiences applying the techniques. In all, the writing team wrote seven books.

“I remember once telling Haim Ginott that living according to his principles is a beautiful way to live,” Ms. Faber said, “but that it was hard. I find myself starting, stopping, tripping over my own tongue. He replied: ‘To learn a new language is not easy. For one thing, you will always speak with an accent. But for your children, it will be their native tongue.’”

Robert Moskowitz, a painter who used the New York City skyline as his muse for work that borders abstraction and representation, died on March 24 in Manhattan. He was 88.

Beginning in the 1970s, Mr. Moskowitz began painting the Empire State Building, the Flatiron Building and, most indelibly, the World Trade Center. Those three buildings appear over and again through the decades, ink black on blue, lavender, orange, yellow or white; in white on black; surrounded by smudgy fingerprints or plumes of smoke; naked in fields of color; rendered in oil, ink, graphite or pastel.

But it was in the imposing modernist stripes of the Twin Towers that Mr. Moskowitz found his great subject, The New York Times said. After the attacks of Sept. 11, 2001, these works took on a darker resonance, and Mr. Moskowitz, whose TriBeCa loft was only a few blocks from the towers, regretfully moved on to other motifs.

The throughline of his career was always his devotion to his art. “All he did was paint,” said the sculptor John Newman, a longtime friend. “It’s all he wanted to do. And when he couldn’t paint, he drove a cab so he could paint some more.”

Amnon Weinstein, an Israeli luthier who restored violins belonging to Jews during the Holocaust so musicians around the world could play them as tributes to those silenced in Nazi death camps, died on March 4 in Tel Aviv. He was 84.

Mr. Weinstein was the founder of Violins of Hope, an organization that provides violins he restored to orchestras for concerts and educational programs commemorating the Holocaust. The instruments have been played in dozens of cities worldwide.

In 2016, Mr. Weinstein was awarded the Order of Merit of the Federal Republic of Germany, one of the country’s highest honors. During the ceremony, Germany’s foreign minister at the time, Frank-Walter Steinmeier, spoke directly to Mr. Weinstein: “A human soul lies behind each of your priceless violins,” he said. “Each violin represents a person. And when your violins play, they represent six million people.”

Marjorie Perloff, whose incisive readings of avant-garde artists like Ezra Pound, John Cage and John Ashbery made her one of the world’s leading scholars of contemporary poetry, died on March 24 at her home in the Pacific Palisades neighborhood of Los Angeles. She was 92.

Professor Perloff, who spend the latter part of her career at Stanford University, made her name as a forceful advocate for experimental poetry, reaching back to early 20th-century writers like Pound and Gertrude Stein and embracing more recent movements like Language Poetry and conceptual poetry.

Throughout her life and even after she took emeritus status from her academic work, she wrote essays, reviews and books, including a translation of notebooks that the philosopher Ludwig Wittgenstein kept during WWI. A few weeks before her death, a new translation of Wittgenstein’s Tractus Logico-Philosophicus was published with a foreword by Professor Perloff.

Famed American artist and sculptor Richard Serra, known for turning curving walls of rusting steel and other malleable materials into large-scale outdoor artworks installed across the world, died on March 26 at his home on Long Island. He was 85.

Known by his colleagues as the “poet of iron,” Serra became world-renowned for his structures of arcs, spirals and ellipses. His works have been installed in landscapes and included in the collections of museums, from the MOMA in New York to the deserts of Qatar. In 2005, eight major works by Serra were installed permanently at the Guggenheim Museum in Spain.

Dr. David Egilman, a physician and expert witness who, over a 35-year span, gave testimony in some 600 trials involving corporate malfeasance, resulting in billions of dollars in awards for victims and their survivors, died on April 2, at his home in Foxborough, MA. He was 71.

A dogged researcher, he dug up incriminating evidence showing that, in many cases, drug companies knew the risks involved with putting a new medication on the market, but went ahead anyway.

In Cincinnati, where he worked with the U.S. Public Health Service, many of his patients were industrial and mining workers who had developed medical conditions after years of working in unsafe conditions. The experience cemented his determination to stand up against medical injustice. His company, Never Again Consulting, was a nod to his father’s experience during the Holocaust as well as the importance of not allowing the horrors of Nazi medical experimentation to be replicated.

Norman Miller, who arrived in Britain via the Kindertransport when he was 7 years old, died Feb. 24 in a hospital in Manhattan. He was 99.

In 1944, when he was 20 , he joined the British Army, hoping to find out what had happened to his family in Germany. Not until after the war did he learn in a letter from a friend who had survived the Jungfernhof concentration camp that his parents, sister and maternal grandmother had arrived there in late 1941, were shot to deaths and buried in a mass grave. Mr. Miller and his son Steven traveled to Riga in 2013, saw the remnants of the camp and went to the forest to fill three vials with soil from the killing fields.

At Mr. Miller’s burial in Paramus, NJ, his sons and other family members poured the soil from his vial onto the coffin after it was lowered into the grave. In his eulogy, Steven Miller said that the purpose of sprinkling the coffin with the Riga soil was “so that they, who were torn from him and never had a proper burial of their own, can finally be prayed over and reunited and laid to rest with their son.”
