Pronounced ROO-dee, Rudy began life as the nimble nickname for the ancient Germanic–Italian Rodolfo/Rudolph, a union of hrōthi “fame” and wulf “wolf,” yet over the centuries he has shed the heavy armor of legend and now saunters through the piazza in rolled-up sleeves, more friendly trattoria host than fearsome lupine hero. Still, a glint of the old wildness remains: parents hear the distant howl of courage in the beloved football film “Rudy,” where grit outshines size, and children catch a wink of North-Pole magic—after all, he’ll only answer to “Rudolph” when Santa takes attendance. In the United States he’s been a steady guest at the naming table since the 1880s, rarely hogging the spotlight but never slipping offstage, most recently lounging around the mid-600s in popularity like a contented Nonno sipping espresso. Short, upbeat, and a shade cheeky, Rudy offers a compact passport to heritage and heart, marrying old-world fame with new-world friendliness in two bright syllables.
