Florence Nightingale is known as a nurse, but she also made a new kind of pie chart showing how many soldiers in the Crimean war died from military action and how many from disease.

It is a marker of how soon she held the respect of her bosses that in 2009, at her request, her design team were relocated from Florence to a new office in her hometown of Rome.

Since they were found last month the cubs have gained weight and even try to offer food to their new mum, who has been named Flo, after the red head singer, Florence Welch.
