“Two ripped Nazi shirts,” Martin Greenfield once said, “helped this Jew build America’s most famous and successful custom-suit company.” Greenfield, who died on Wednesday, was once known as Maximilian Grünfeld, “a skinny Jewish prisoner whose job was to wash the clothes of Nazi guards” at Auschwitz. The story of his life afterward “exemplified the classic tale of immigration to America,” writes Alex Traub.

He was finally freed in 1945 by America soldiers.

General Eisenhower himself toured the camp, unaware that a teenage prisoner there would one day become his tailor. In his memoir, Mr. Greenfield recalled thinking that Eisenhower, an ordinary 5-foot-10, was 10 feet tall.

After that, he made his way to America, changed his name to Martin Greenfield to sound “all-American,” learned to make suits, eventually built the last surviving union clothing business in New York City, and was named “America’s best tailor by GQ, Vanity Fair, and CNN.”

Over the decades, he made suits for Gerald R. Ford, Bill Clinton, Barack Obama, Donald J. Trump, Joseph R. Biden, Colin Powell, Ed Koch, Michael R. Bloomberg, Frank Sinatra, Paul Newman, Martin Scorsese, Denzel Washington, Michael Jackson, Lebron James, and Leonardo DiCaprio, among many others.

On his first day in Auschwitz, Max’s father, Joseph, told him that he was more likely to survive if they separated, Mr. Greenfield wrote in his memoir. The next day, the camp guards asked which prisoners had skills. Joseph grabbed Max’s wrist, thrust the boy’s hand in the air and announced, “A4406”—Max’s tattooed inmate number. “He is a mechanic. Very skilled.”

Two German soldiers hauled Max away. He did not see his father again.

Before they parted, Joseph said to Max, “If you survive, you live for us.”

The rest of Mr. Greenfield’s life was an attempt to follow that commandment, his son Tod said: “And that’s what he did.”

Considering the current state of Israel-Arab relations, Ghaith al-Omari writes

First and foremost, no ceasefire will be possible without the release of Israeli hostages and commitments to disarm Hamas and remove it from power. The final say on these matters rests with Hamas commanders on the ground in Gaza, who have been largely impervious to foreign pressure so far. At minimum, however, the United States should insist that Qatari and Egyptian mediators push Hamas’s external leadership to accept these conditions publicly, which could increase pressure on the group’s Gaza leadership.

Washington should also demand a clear, public position from key Arab states regarding disarmament. The Palestinian Authority President Mahmoud Abbas endorsed this position in a June letter to Saudi Arabia and France, giving Arab states Palestinian cover for endorsing it themselves.

Some Arab states have already indicated a willingness to play a significant role, but they will have little incentive to commit resources and personnel to Gaza unless Israel (1) provides guarantees that it will not occupy the Strip indefinitely, and (2) removes its veto on a PA role in Gaza’s future, even if only symbolic at first. Arab officials are also seeking assurances that any role they play in Gaza will be in the context of a wider effort to reach a two-state solution.

On the other hand, Washington must remain mindful that current conditions between Israel and the Palestinians are not remotely conducive to . . . implementing a two-state solution.
