Charles Darwin, he'd probably be flabbergasted at the fact that some scientist misinterpreted his work.
Not sure what you mean by that, stating the nature of the "misinterpretation" may be much more informative than you know, throwing out a very vague statement.
Anyway, I'd go with Dr. Guillotin, who invented the famous execution device as a means of delivering a relatively painless humane means of execution. He in no way intended it to be used as a symbol of terror by bloody revolutionaries executing innocents on nothing but base suspicion.
