Fascinating quote from page XXXIII of Peter Bernstein’s 1996 book “Against the Gods: The Remarkable Story of Risk” (cf. https://www.amazon.com/Against-Gods-Remarkable-Story-Risk/dp/0471295639/):
“The earliest known work in Arabic arithmetic was written by alKhowarizmi, a mathematician who lived around 825, some four hundred years before Fibonacci. Although few beneficiaries of his work are likely to have heard of him, most of us know of him indirectly. Try saying “alKhowarizmi” fast. That’s where we get the word “algorithm,” which means rules for computing.”
