Lew Klein, a broadcast pioneer and longtime educator for whom Temple’s Klein College of Media and Communication is named, made an indelible mark on his industry, on Temple and on the world. Generations of alumni in broadcasting and journalism credit him with helping to launch their careers, and his impact was felt deeply in that community and beyond.

Many of those who knew Klein personally took to Twitter to share their memories of him when the news of his passing broke last week. Here’s a roundup of some of their touching posts about the significance Klein had on careers and lives.

Philly - and @TempleUniv - have lost an icon. Lew Klein, broadcasting pioneer, is dead at 91. I was honored to be inducted into the @TUKleincollege alumni hall of fame in 2015 with an award named for Mr. Klein, and was struck by his wisdom and kindness. https://t.co/WdKsCzLimi

The Police Athletic League, and indeed Philadelphia, lost a legend.

Longtime PAL Board member Lew Klein has passed away.

Textbooks will be written, and likely taught at Temple University’s Klein College on the impact Lew made in the worlds of television and media. pic.twitter.com/nARR6jqxJz
