Second seeds Kveta Peschke and Katarina Srebotnik claimed the women's doubles title at Wimbledon this evening, while American twins Bob and Mike Bryan won the men's title.
Czech player Peschke, 35, and Slovenian Srebotnik, 30, beat Germany's Sabine Lisicki and Australian Sam Stosur 6-3 6-1.
The Peschke-Srebotnik partnership began competing as a team in grand slams last year and reached the 2010 French Open final, losing to Serena and Venus Williams.
They have remained competitive through the past year and today's victory secured what for both players was a first women's doubles grand slam title.
Srebotnik had previously won five mixed doubles slams, but today brought her first Wimbledon success.
German Lisicki, who impressed in reaching the women's singles semi-finals before losing to Maria Sharapova on Thursday, struggled to rediscover that form and the match was decided when her serve was broken in the final game.
Lisicki and Stosur had taken an early lead in the opening set but were then overwhelmed.
Srebotnik was taken aback by the achievement, saying: 'It's impossible to describe. It hasn't sunk in.
'We've been waiting for this a long, long time. I've been in four (women's doubles) finals before. You want to get that grand slam under your belt.'
The champions are also set to become the new world number one pairing.
'To be number one is a dream of every player, whether in singles or doubles, and we're very proud of that,' Srebotnik said.
'Through the whole tournament we played extremely well. Today we kept our nerves. Even though we were down 1-3 in the first set we believed and knew we could win it.
'Winning a grand slam here at Wimbledon is for me a special moment.'
Later, the American twins Bryan claimed a record-equalling 11th grand slam doubles title with a straight-sets victory over Sweden's Robert Lindstedt and Romania's Horia Tecau.
The manner of their victory on Centre Court was straightforward, with the number one seeds rarely looking troubled on their way to a 6-3 6-4 7-6 (7/2) win.
The victory ended a three-year losing streak in the final at SW19 and also equalled Mark Woodforde and Todd Woodbridge's record of winning 11 grand slams.
After enduring an energy-sapping route to the final - two of their matches went to lengthy fifth sets - the Bryans were relieved to wrap up victory inside three sets.
'After yesterday's semi-final (when they beat Michael Llodra and Nenad Zimonjic 9-7 in the final set) we didn't have a lot in our legs,' said Mike Bryan.
'We knew we had to finish it off in three or four today. It was a tough week. One match was two days long and we won it 16-14 in the final set.
'We've lost three heartbreaking finals here so to get on that board again, to have two Wimbledon titles, is really special.'
The pair, aged 33, now hope to move ahead of Woodforde and Woodbridge by winning the US Open later this year.
'To equal the Woodies, a team that we idolised, the greatest team in our mind, is unbelievable,' Mike Bryan added.
'We'd love to try to get to 12 and do that at the (US) Open.'
