Phil and Susan Ershler became the first couple to finish the Seven Summits together when they reached the Summit of Everest on May 16th, 2002. Pretty nice! Doing all the climbs together! A nice picture of them coming down the mountain is above. (Picture source: Eric Simonson). Susan is now an very successful motivational speaker.
So for those that like to split hairs. Gary Pfisterer and Ginette Harrison did finish the Seven Summits back in 1995, but some of their Summits were not together and some were before they were married.
Ginette Harrison, of course, was one of the greatest women climbers ever, and is still the only woman to summit Kangchenjunga. Ginette, never got the big media attention but climbed mountains in small groups of climbers in most cases rather than on commercial expeditions.
