A statement on the Dame Vera Lynn Children’s Charity website confirmed her passing. The comments were noted by CNN.

“We are devastated that we have lost our President, Dame Vera Lynn, who passed away peacefully, aged 103, surrounded by her close family,” the statement read.

Lynn lived in Ditchling, East Sussex, England, and was widely beloved by people in the U.K. She also became the first English singer to make it the number one spot on American music charts.

In 2017, she also became the oldest musician to be appear in the top-10 British charts with “100,” which came out in honor of the singer’s 100th birthday. Lynn was also an advocate for those who suffer from cerebral palsy and other disabilities.

“My mother first became involved in raising awareness of cerebral palsy in the 50s when there was very little understanding of the condition and children who suffered from motor learning difficulties were often referred to rather pejoratively as ‘spastic,'” a statement from her daughter Virginia Lewis-Jones read, per CNN.

“Along with celebrity chums including David Jacobs and Wilfred Pickles, she set out to change people’s attitudes towards the disability and help children reach their full potential,” she added. “There was no one else raising funds to help at that time, so it was groundbreaking work.”
