El Puente founder Luis Garden Acosta passed away on Tuesday night, the organization shared on their website.
Acosta, 73, was surrounded by friends and family when he passed away peacefully.
The longtime community leader co-founded El Puente in 1982 to address the violence crisis happening in the Southside.
Nearly four decades later, El Puente has become a community staple, still doing important work on education and youth development, the environment and more.
Elected officials remembered Acosta as a visionary and transformative leader in Brooklyn.
