DUBLIN — Doris “Granny D” Haddock died peacefully in her Dublin family home at 7:18 p.m. on March 9, 2010. She was 100 years old.

Born in 1910 in Laconia, she attended Emerson College and lived through two world wars and the Great Depression. She was an activist for her community and for her country, remaining active until the return of chronic respiratory problems four days ago.

She walked across the United States at the age of 90 in the year 2000, in a successful effort to promote the passage of the McCain-Feingold Campaign Finance Reform Act. In 2004, Granny D decided to challenge incumbent Sen. Judd Gregg for his U.S. Senate seat. She hoped to demonstrate that ordinary people can run for office and win with the support of small donations from individuals. Despite a shortened, grassroots campaign without the benefit of any advertising dollars, Granny D garnered an impressive 34 percent of the vote.

During the past five years, Granny D traveled the country speaking about campaign finance reform and working on behalf of legislation for publicly-funded elections in New Hampshire.

In the 1960s, she and her husband, James Haddock Sr., were instrumental in halting planned nuclear tests that would have destroyed a native fishing village and region in Alaska.

She had just completed two short books, a memoir titled “My Bohemian Century” and “My Sources of Strength,” which will be published by her family.

She raised two children, the late Elizabeth Lorentz and a son, Jim Haddock, who survives her and, with his wife, Libby, was at her side during many of her great adventures, including the final one this week. She is also survived by her 98-year-old sister, Vivian Mack of Port Lucie, Fla., eight grandchildren and 16 great-grandchildren.

A public memorial service will be held at a later date.
