The first recorded use of sonar was in the time of Da Vinci - 1490. Stick a hydrophone in the water and listen to see what you can hear. That's sonar. It was left until the early 1900's when the Titanic sunk that sonar was looked at to aid marine navigation. The development of submarines at about this time caused the military to investigate it. Electronics was growing up in the same period, and all these factors combined to bring us "modern" sonar. A link to the Wikipedia article is provided, and the "History" portion of the post is short and easy to read. Why not surf on over and check it out?
