Catherine Bellis and Marketa Vondrousova, the youngest team in the quarterfinals, are playing their first senior event together. The 18-year-olds are resuming a successful doubles partnership that yielded them a Roland Garros junior runner-up plate in 2014, the Orange Bowl title in the same year and a 11-3 record overall.
Chan Yung-Jan and Martina Hingis only teamed up in February - but the duo have already swept to five titles and a 36-5 win-loss record. They are currently riding a ten-match winning streak and are unbeaten on grass so far following trophies in Mallorca and Eastbourne.
No.2 seeds Ekaterina Makarova and Elena Vesnina are the longest-standing partnership in the quarterfinals. The Russian pair first teamed up in the 2008 Fed Cup final, when they helped Russia shut Spain out 4-0 to take the trophy, and they have played full-time alongside each other since May 2012. In that time, Makarova and Vesnina have won two Slams (Roland Garros 2013 and the 2014 US Open), a gold medal in the Rio de Janeiro Olympic Games and three further Slam finalist places, including Wimbledon 2015.
Chan Yung-Jan and Martina Hingis hold a 3-0 record against their quarterfinal opponents, Anna-Lena Groenefeld and Kveta Peschke, including a 6-2, 6-0 win in the Eastbourne quarterfinals two weeks ago.
Ashleigh Barty and Casey Dellacqua completed their set of Slam runner-up plates at Roland Garros this year, having already reached the finals of the Australian Open, Wimbledon and US Open in 2013. Dellacqua is 0-7 in Slam women's doubles finals overall - though the Australian did win the 2011 mixed doubles crown alongside Scott Lipsky.
Renata Voracova is playing her 45th Slam doubles main draw with her 24th Slam partner, Makoto Ninomiya, at Wimbledon - and has been rewarded with her maiden quarterfinal. The Japanese-Czech duo are playing only their second event together following the ITF $100,000 tournament in Southsea two weeks ago.
Chan Hao-Ching and Monica Niculescu are another pair in the quarterfinals who teamed up in this year's grass swing. The Taiwanese-Romanian pair had played just one match, a first-round loss at Eastbourne, before arriving in London.
Chan Yung-Jan and Martina Hingis have been the most dominant pair in the tournament so far: they are yet to drop a set and have conceded just 12 games in three matches.
2013 runners-up Ashleigh Barty and Casey Dellacqua take on 2015 runners-up Ekaterina Makarova and Elena Vesnina today. Barty and Dellacqua won the only meeting between the teams to date, 6-2, 6-3 in the quarterfinals of the 2013 US Open.
Kveta Peschke is playing her 60th Slam doubles main draw at Wimbledon, the most of any of the quarterfinalists. The Czech made her doubles debut with Eva Melicharova at Roland Garros in 1994 and has won one women's doubles Slam, with Katarina Srebotnik at Wimbledon 2011. Alongside current partner Anna-Lena Groenefeld, she was won four titles, and the pair's best Slam showing is a semifinal run at Wimbledon 2013.
Johanna Konta lit up Centre Court in becoming the first British woman to make the Wimbledon semifinals since Virginia Wade in 1978 - but a festival atmosphere was also brewing outside despite the torrential conditions. Carrie Dunn braved Henman Hill - or Konta Contour, as it should perhaps now be known - to talk to the British No.1's fans.
Inside Centre Court, Paul MacInnes wrote about how Konta won British fans' hearts over the course of her dramatic win for The Guardian.
Yesterday, Simona Halep's quarterfinal loss to Johanna Konta ensured that Karolina Pliskova will become the 23rd WTA World No.1 after Wimbledon. Look back on her journey to the top here.
