One of the greatest forgotten stories in Boston sports history

Every October, without explanation or return address, an envelope arrived at Edward “Red” Mahoney’s home containing two front-row season tickets to the Boston Bruins — seats directly on the glass. Red never explained where they came from, and he rarely spoke about his past.

Decades after Red’s death, his grandson discovered a shoebox filled with old photographs, launching a search that uncovered far more than a family mystery. Hidden behind those anonymous Bruins tickets was the story of a working-class kid from Hyde Park, Massachusetts who became one of the brightest stars in amateur hockey, and a close friend of one of the most influential and least celebrated figures in Boston sports history, Walter Brown.

Glass Seats: Walter Brown and the Forgotten Amateur Stars Who Built Hockey in Boston tells the remarkable true story of two men whose lives intersected during the formative years of American hockey. Red Mahoney was there as a player, coach, witness, and trusted friend. Walter Brown, future founder of the Boston Celtics, breaker of the NBA’s color barrier, and namesake of the championship trophy awarded to every NBA champion, was the visionary determined to build something lasting.

Drawing on years of research, including newspaper archives, historical databases, and collaboration with historians, Glass Seats uncovers a forgotten chapter of sports history: the battles over amateurism, the nearly forgotten 1933 World Championship, and the untold story of Boston sports before the dynasty years.

This deeply personal work of narrative nonfiction blends sports history, biography, and family discovery into a compelling story about legacy, memory, and the people history almost forgot.

“Some men learn caution from experience. Walter Brown was not one of those men.”— Glass Seats

Where it began

Who were the men in the photograph?

Matthew Gentile did not set out to write a book. He set out to identify the men standing beside his grandfather, Ed “Red” Mahoney, in a poorly cropped photograph marked only by a uniform reading OLYMPICS.

One question opened the door to an extraordinary forgotten chapter of Boston sports history.

The author’s journey

A family mystery became a mission.

What began in a shoebox of old photographs became years of research, interviews, archival discoveries, and a deeper understanding of the men who built hockey in Boston.

Matthew Gentile is a lifelong Boston sports fan and the grandson of Edward “Red” Mahoney. Born in Boston and raised in Texas, he has spent the past two decades living in Florida but has always felt a strong connection to Boston’s rich sports history, inspired in part by the grandfather he never had the chance to know. A devoted Celtics and Red Sox fan, Matthew grew up hearing fragments of his grandfather’s story from family members and spent years researching the forgotten world Red inhabited through hundreds of newspaper archives, journals, books, historical databases, and conversations with hockey historians.

Driven by a desire to uncover the truth behind his grandfather’s mysterious connection to the Boston Bruins, Matthew pieced together a remarkable story about the early days of American hockey and the overlooked figures who helped shape Boston sports history.

He lives in Tampa, Florida, with his wife and three children.
