"My father Abe, 98, passed away this evening," Schumer said in a post on Twitter with a picture of his family.
"In so many ways—he personified the greatest generation. He took whatever was thrown at him no matter how difficult, did his job, never complained. An amazing husband, parent, grandparent, great-grandparent," Schumer said.
"We love him & will miss him."
Condolences were sent to Schumer from both sides of the political aisle following the news of his father's death.

Abe Schumer and his wife Selma raised three children in the Brooklyn borough of New York City, the Senate majority leader's website states.
Abe Schumer grew up in Utica, N.Y., and served in World War II as a radio operator. After the war, he took over his father's exterminator business. Schumer, who was born on Thanksgiving Day in 1950, told reporters earlier this week in Brooklyn that his father was hospitalized in Long Island undergoing a heart procedure. The father and son shared a close relationship, and Schumer had planned to spend time with him on Thursday.

But Schumer said his father was happy once he retired and happiest of all when he was with his great-grandson: "But then he retired and then he became a happy guy. And you know, the greatest joy in his life is his great-grandson. For a year he couldn't see him, then they got the shots, they're over 85, and for the first time he saw him on Sunday — what a joy."
The elder Schumer, who also left two granddaughters and one great-grandson, died after Charles Schumer's 71st birthday on Tuesday.
