Alida Bosshardt, who spent more than 50 years working for the Salvation Army and established a center in Amsterdam's Red Light District for sex workers and drug addicts, has died. She was 94.

Bosshardt died Monday, Salvation Army spokeswoman Hella van der Schoot said. "She had heart troubles and kidney problems," she said.

Bosshardt joined the Salvation Army in 1934 and was instructed to work with women in the Red Light District shortly after the end of World War II.

 She established a "Goodwill" center in the district that eventually became a place where troubled people came for shelter and social services - prostitutes and their children, the homeless and drug addicts.

She retired in 1978 at age 65, but continued volunteering until shortly before her death.

Among Bosshardt's many awards were a knighthood in the Netherlands. The Israeli Holocaust museum gave her an award for helping Jewish children during the war, often taking them on her bicycle to homes where they would go into hiding.
