Word is spreading on Twitter that Michael C. Gross, the man who created the infamous “No Ghosts” logo for Ghostbusters has passed away after a battle with cancer. We also reached out to someone who explained that they have been working with Gross recently and they confirmed his passing. He was 70 years old.

Gross was the art director for National Lampoon magazine for several years and also acted as producer on films such as Heavy Metal, Kindergarten Cop, Twins, and more.

His logo for Ghostbusters has become one of the most iconic images in the world, one that nearly everyone knows upon sight. It was used heavily in merchandising, video games, and cartoons based off the 1984 supernatural comedy film. The first film was a box office smash, becoming one of the most successful comedies of the 80’s and cementing the film’s place in film history. The sequel, which was released in 1989, fared nearly as well and still remains a beloved sequel.

We send our condolences to his friends and family. Rest in peace, Mr. Gross. You ain’t afraid of no ghosts indeed.
