It is with great sorrow that we share the news that Alex Rothwell, an Explo alum, has passed.

For the past two summers, Alex attended both Explo at St. Mark's and Explo at Wellesley. His mother reports that he left Explo this summer with tremendous enthusiasm — and was already planning the courses he would take next summer.

Alex was an important member of the Explo community, and we convey our deepest sympathy to his parents, Susan and Jim Rothwell, as well as his brother Zachary, who attended Explo at St. Mark's this summer.

Below, with the blessing of his family, we're reprinting Alex's obituary as it appears on

Alexander Falcon Rothwell of Westport and Remsenburg, N.Y., died unexpectedly on Aug. 12. He was 13.

“His death devastates those he touched, yet our hearts overflow with the utmost pride in his life — in his intelligence, his wit, his energy, his beauty, and his unwavering faith in his ideas.”

A celebration of Alex’s life will be held Saturday, Aug. 24, at 11 a.m. at the Unitarian Church in Westport.
