Chicago is mourning the loss of Pete Kastanes, a widely respected local historian and the driving force behind Vanished Chicagoland, whose passion for preserving the city’s past made him a beloved figure among history enthusiasts across the region and beyond.
News of Kastanes’ passing, shared Sunday, has prompted an outpouring of tributes from followers, collaborators, and admirers who credit him with bringing Chicago’s forgotten stories back to life. While official details surrounding the cause of death have not been publicly disclosed, the sense of loss is being felt deeply throughout the community he helped build.
Kastanes was best known as the creator and curator of Vanished Chicagoland, a widely followed Facebook group and digital platform dedicated to documenting and celebrating the city’s rich—and often overlooked—history. Through photographs, personal accounts, and carefully researched posts, he created a space where longtime residents and newcomers alike could reconnect with the Chicago of earlier generations.
To many, Kastanes was more than a historian—he was a storyteller who understood that the city’s identity lives not only in its skyline, but in its neighborhoods, businesses, and everyday memories. His work highlighted everything from long-closed restaurants and demolished landmarks to the cultural shifts that shaped Chicago over the decades.
Friends and followers describe him as deeply committed to his mission. His goal, they say, was simple but powerful: to share Chicago’s history with the world and ensure that its stories were not lost to time. That commitment helped Vanished Chicagoland grow into a vibrant community, connecting thousands of people through shared nostalgia and civic pride.
Tributes continue to pour in across social media, with many crediting Kastanes for inspiring their own interest in local history and preservation. For some, his work served as a daily reminder of the city’s evolving character; for others, it offered a personal connection to places and moments long gone.
Those who worked alongside him or followed his content say his influence extended beyond the posts themselves. He fostered a sense of community, encouraging others to contribute memories, photos, and stories—turning history into a collective, living archive.
As Chicago reflects on his passing, many are expressing a shared commitment to continue the work he championed: preserving the city’s heritage and sharing its stories with future generations.
Funeral arrangements and memorial service details have not yet been announced. Family members and close friends are expected to release additional information in the coming days.
Pete Kastanes is being remembered as a passionate historian, a community builder, and a true ambassador of Chicago’s past. For those who knew him—and for the countless others who discovered the city through his work—his legacy will endure in every story told, every memory shared, and every piece of Chicago history kept alive.
