"Premature optimization is the root of all evil." is a popular quote with mysterious origins. It is widely attributed to Donald Knuth, who >>apparently >>used it in >>Structured Program with goto Statements but later >>credits Tony Hoare.

Hoare, however, did not claim it when I queried him in January of 2004:

Dear Hans,

I'm sorry I have no recollection how this quotation came about.� I might have attributed it to Edsger Dijkstra.

I think it would be fair for you assume it is common culture or folklore.

Tony.

>>Bruce Eckel also >>credits Dijkstra. Now that would be ironic, since the widely-attributed first use by Knuth was written as a rebuttal to Dijkstra's >>Go To Statement Considered Harmful.
