John Hempel could refer to various individuals, but without specific context, it's difficult to determine which one you mean. If you're referring to someone notable in a particular field (such as science, sports, politics, etc.), please provide more details so I can assist you better. If it's a fictional character or a lesser-known individual, additional context would also be helpful.
