Display PDF files inside Joomla Content/Article

I was recently working on a Joomla based web site design for a client, and he had requested that the site display PDF files he provided me inside articles for his portfolio pages on his web site.

My first thought was there would be some kind of a plugin/module to extend Joomla to display a PDF file in joomla, but was not able to find any that worked for me. Then I had a brainstorm.
