Portland Trailblazers and Seattle Seahawks owner Paul Allen is dead at 65, following an unsuccessful battle with non-Hodgkin's lymphoma, per NBA.com.

Allen, who purchased the NBA outfit in 1988 and took charge of the NFL's Seahawks in 1996, was also a part owner of MLS club Seattle Sounders and co-founded Microsoft alongside Bill Gates in the early 1970s.

The deceased magnate was successfully treated for Hodgkin's lymphoma in 1982 and then non-Hodgkin's lymphoma in 2009. But, earlier this month, he revealed having started treatment for a recurrence of non-Hodgkins lymphoma and unfortunately passed away on Monday.

“My brother was a remarkable individual on every level," his sister Jody Allen said in a press release. "While most knew Paul Allen as a technologist and philanthropist, for us he was a much loved brother and uncle, and an exceptional friend.

"Paul’s family and friends were blessed to experience his wit, warmth, his generosity and deep concern.

"For all the demands on his schedule, there was always time for family and friends. At this time of loss and grief for us – and so many others – we are profoundly grateful for the care and concern he demonstrated every day."

At the time of his death, Allen was estimated to be the 46th richest person in the world. His love and passion for sports saw him spend $70 million to acquire Blazers in 1988 and the team reached the NBA Playoffs 19 times under his ownership, boasting a win percentage of 56.2. They also went to the NBA Finals in 1990 and 1992.

 

“Paul Allen was the ultimate trail blazer – in business, philanthropy and in sports," NBA Commissioner Adam Silver said in a statement released by the league.

"As one of the longest-tenured owners in the NBA, Paul brought a sense of discovery and vision to every league matter large and small.

"He was generous with his time on committee work, and his expertise helped lay the foundation for the league’s growth internationally and our embrace of new technologies.

"He was a valued voice who challenged assumptions and conventional wisdom and one we will deeply miss as we start a new season without him. Our condolences go to his family, friends and the entire Trail Blazers organization.”

Trailblazers star point guard Damian Lillard has also paid his respects to Allen.

"At a loss for words," he wrote as the caption of an Instagram post. "RIP to a great man... much love and Respect!"
