The hydrophone was developed first. It was around back in Da Vinci's time, and the first recorded use dates from about 1490. Stick the large end of a "horn" of some kind in the water and listen to the little end to see what you can hear. That's a hydrophone. Sonar came along later, like in the early 1900's. It was being developed at the time electronics was advancing, and it is with the application of modern electronics that we can make the most effective use of this remarkable imaging tool. A link is provided to the Wikipedia article on sonar, and the "History" part of the article is short and easy to read.
