Question

who discovered pdf ​

Answer 1

HEY Mate..

PDF was invented and not discovered:-!

PDF was developed in the early 1990s as a way to share documents, including text formatting and inline images, among computer users of disparate platforms who may not have access to mutually-compatible application software. It grew out of a system called "Camelot" developed by Adobe's co-founder John Warnock.
