This word will be used to describe people who are smart, funny, charming, personable, attractive, all-round great folks who succeed without making you feel like you're worthless. A positive word to describe positive people who make us all better by proxy.
e.g. It's great to work with Jill; she's the hadfield in our office. Reginald is such a hadfield! I hope my kids grow up to be like him.
I spotted a hadfield crest bumper sticker.
