Bob Sheppard, whose elegant intonation as the public-address announcer at Yankee Stadium for more than half a century personified the image of Yankees grandeur, died Sunday at his home in Baldwin, on Long Island. He was 99.

His death was confirmed by his son Paul.

From the last days of DiMaggio through the primes of Mantle, Berra, Jackson and Jeter, Sheppard’s precise, resonant, even Olympian elocution  he was sometimes called the Voice of God  greeted Yankees fans with the words, “Good afternoon, ladies and gentlemen, and welcome to Yankee Stadium.”

“The Yankees and Bob Sheppard were a marriage made in heaven,” said Paul Sheppard, a 71-year-old financial adviser. “I know St. Peter will now recruit him. If you’re lucky enough to go to heaven, you’ll be greeted by a voice, saying: ‘Good afternoon, ladies and gentlemen. Welcome to heaven!’ ”

In an era of blaring stadium music, of public-address announcers styling themselves as entertainers and cheerleaders, Sheppard, a man with a passion for poetry and Shakespeare, shunned hyperbole.
