Philippa Campsie lived in Paris as a student, studying French history and literature at the Sorbonne, and staying in a chambre de bonne with a view of the tip of the Eiffel Tower. She never got the city out of her system after that and returns regularly with her husband, Norman Ball. Since 2010, she and Norman have written about Paris on a blog called "Parisian Fields" (https://parisianfields.com/). They like to get beyond basic tourist information, and draw on her experiences in urban planning and his knowledge as a historian of technology to explain features of the city's streets, and tell the stories of people who contributed to the life of the city. Philippa started creating tours for VoiceMap in 2015. Currently, she is carrying out research in Paris on the history of the education of blind people (the first school for the blind was founded in Paris) and the invention of braille. One day she hopes to create a tour for visually impaired visitors to the city.
