A friend sent me a picture from 1980. It's not that clear. I was wondering if there was a program that can make it sharper?

There are many programs that can do that. Many photo editing programs allow to subject graphics to filters, that increase perceived sharpness. In GNU Image Manipulation Program, Gimp, one filter is "Sharpen (Unsharp mask)", which is found under "Filters - Enhance".
Keep your expectations realistic. These filter can enhance the perceived quality of an image, but they cannot restore information that is not anymore there. You should experiment with the settings to obtain a result that is visually more pleasing but still looks natural.
