Martin Greenfield, Holocaust survivor, tailor to six presidents and countless celebrities and North Hills resident, died March 20 at a hospital in Manhasset. He was 95.

“His memory will be a fond memory for everyone who knew him,” said North Hills Mayor Marvin Natiss, who was a friend of Greenfield for around 50 years. “He was just a gentleman and always had a smile on his face and was always happy to be here. And 95 was a nice age, longstanding, and he was just a wonderful man.”

For such a kind man, Greenfield endured horrors in his early life. It was in the Auschwitz concentration camp that he first learned how to sew.

As a teenage Jewish prisoner in the camp, then Maximilian Grünfeld was assigned laundry duties. One day he accidentally ripped the collar of a guard’s shirt in the laundry room. The guard whipped Max in response and threw the shirt at him.

A fellow prisoner taught Max how to sew. He mended the collar of the shirt and, instead of returning it to the guard, slipped it under his prison uniform for safekeeping.

That shirt altered the course of Greenfield’s life. It led to his decades-long career as a tailor, but it also made other prisoners think Greenfield had some sort of special status, so he was allowed to roam the grounds of Auschwitz by the guards and authorized to take extra food from the hospital kitchen.

He later ripped another guard’s shirt on purpose.

“Two ripped Nazi shirts,” Greenfield wrote years later in his memoir, “helped this Jew build America’s most famous and successful custom-suit company.”

Greenfield opened Martin Greenfield Clothiers in Brooklyn in the late 1970s, an old-school tailor shop that did all its manufacturing in-house.

Martin Greenfield Clothiers is New York City’s last surviving union clothing factory, Greenfield’s son Tod Greenfield told The New York Times.

Around 50 garment workers are employed at the store and work tirelessly on custom-made suits, which each take about 10 hours of work.

His suits are a hot commodity, since Greenfield’s shop is one of the only places New York City’s wealthy and famous can find hand-manufactured suits.

Even his friend, Natiss, was a loyal customer.

“I’ve been wearing Martin Greenfield suits and blazers for the last 25, 30 years,” Natiss told Blank Slate Media.

In his memoir, Greenfield wrote that he worked alongside figures from the Gerald R. Ford, Bill Clinton, Barack Obama and Donald J. Trump administrations to Frank Sinatra, Martin Scorsese, Denzel Washington, Michael Jackson, Kobe Bryant and the 7-foot-1 Shaquille O’Neal, who “required enough suit fabric to make a small tent.”

Natiss shared a fond memory from a suit-fitting at the shop.

“My fondest memory, honestly, is when his son Jay was fitting me for a suit and Martin came over and said to Jay, ‘Don’t you see his waist line is a little bit lower than his belt line?’” said Natiss. “So he says, ‘You have to take the measurement here, not up here,’ and I still laugh about it.”

Martin Greenfield Clothiers fashioned suits for a number of television shows and films, as well, including the cast of “Boardwalk Empire,” “Billions,” “The Great Gatsby” and “The Wolf of Wall Street.” Greenfield even created the red suit and orange vest for the title character in the 2019 “Joker” film.

His sons, Tod and Jay Greenfield, now run the shop.

Jay said what he will miss most about his father is his ability to connect with people.

“I looked at our social media feedback and…saw the thousands of people commenting and saying how touched they were and I thought…my father never opened a computer in his life. He never had a phone that wasn’t just for talking on,” Jay told Blank Slate Media. “And somehow every one of those people, he made an impression on.”

Greenfield was born on Aug. 9, 1928, in Pavlovo, which was then in Czechoslovakia and is now in western Ukraine. As a young teen, the Nazis forced him and his family onto a train to Auschwitz. He and his father were separated from his mother, two sisters and brother.

He remained with his father only briefly. On his first day in Auschwitz, Max’s father, Joseph, told him he was more likely to survive if they separated, Greenfield wrote in his memoir.

So when camp guards asked which prisoners were skilled the next day, Joseph grabbed Max’s wrist and raised his hand in the air, saying that “A4406” is a skilled mechanic.

Max was taken away and he never saw his father again. Joseph’s last words to his son? “If you survive, you live for us.”

Max was the only member of his family to survive. And his son, Tod Greenfield, told The New York Times his father spent his life trying to follow those words: “And that’s what he did.”
