Henry Searle ends Britain's 61-year wait for Wimbledon boys' success
Searle, who fired nine aces and 22 winners to wrap up the win in 83 minutes, claimed the title without dropping a set in the tournament.
"It's amazing to play on Court One," said Searle, who beat four seeded players en route to the title.
"It's a pretty special feeling, it's not going to come too often. I'm going to enjoy it in front of this crowd. I'll keep working hard and we'll see what happens."
Britain's last boys' title at the grass court Grand Slam came when Stanley Matthews, son and namesake of the Ballon d'Or-winning footballer, won in 1962.
