Well, a surd is a number that cannot be simplified by extracting a square or cube root. √2 (square root of 2) can't be simplified further so it is a surd. If that is the word you meant, they have been recognized for as long as math has been around using Arabic numbers- several thousand years. Do not know of a single person that said "Hey! That is a surd!" The name of the person is lost to time.
Surds are normally irrational numbers.
No. Surds are a part of maths, and are the opposite of powers.
Roots that are irrational are called surds. There are irrational numbers that are not surds since they are not roots of any equation. For example, Pi. Rational roots, such as square root of 4, are not surds.

Whoever it was who discovered that if you had a square whose sides were one unit long, the lengths of its diagonals were sqrt(2) - surds!

No, surds can never be negative.
