How was it discovered? When people sought a method of turning multiplication into addition, like Azzajazz said... It was the invention of John Napier.

1610s, Modern Latin logarithmus, coined by Scottish mathematician John Napier (1550-1617), literally "ratio-number," from Greek logos "proportion, ratio, word" (see logos) + arithmos "number" (see arithmetic).

a=5.7895
b=2.2358
a*b= 12.9441641

I have Casio fx991MS. Using it, I found:

log a = .762641058
log b = .349432951
log a + log b = 1.112074009

antilog 1.112074009 = 12.94416407
