The Central British Fund (CBF) put together a large team of people to look after the Boys.
The Boys were teenage and child-Holocaust survivors, who were brought to the UK after the war for rest and rehabilitation.
The British government offered 1,000 visas to bring the Boys to the UK but the caveat was that the CBF were responsible for their care and would pay all the expenses.
Fellner was a key member of the Committee for the Care of the Concentration Camp Children. She accompanied the Boys who were flown from Prague to Prestwick in February 1946.
She was also a member of the Jewish Refugees Committee.
She then worked on arranging the Boys’ emigration as their two year visas ran out.
She was later Mrs. Puritz.
Fellner died in 1966 at the age of 51.
