BAYFIELD, Wis. (AP) -- A retired school teacher from northwestern Wisconsin has now climbed the tallest mountains on each of the seven continents.

A dispatch from Alpine Ascents International reported that Bayfield's Lori Schneider reached the 29,035-foot-high peak of Mount Everest at about 7:30 p.m. Friday Central time. It's the tallest point in the world.

The 52-year-old climbed six of the mountains after being diagnosed with multiple sclerosis in 1999.

Schneider is reported to be the first woman afflicted with the neurological disease to reach the Everest summit and the first person with MS to complete the Seven Summits.
