I am a Family Physician, born and raised in Puerto Rico, and practicing for almost 28 years.
Much like Babydoc (post Dec., 2004), my grade school years, back in the 50's, were taught with Fountain Pen in hand (popular models were the Esterbrooks, which I still have, Parker 51's and Sheaffers), and the Palmer Method of handwriting was the method we learned.
I've been using FP's ever since (ball points tend to slip and roll in my hand!)
Even though Med School somewhat "ruined" my handwriting, I've been trying to get back in shape, practicing the Palmer again, with a little ad-mixture of Peterson's Method (they are somewhat similar in appearance, although their approach is quite different).
