Frederick George Miles was a British aircraft designer and manufacturer who designed numerous light civil and military aircraft and a range of prototypes. The name "Miles" is associated with two distinct companies that Miles was involved in and is also attached to many non-aviation products such as the Biro pen, photocopiers and book binding machinery. Throughout his life, he was known as "Miles" and never by his first name, even to his own family, although Don Brown refers to him as "F.G.", presumably to distinguish him from his brother George.

Maxine Frances Mary "Blossom" Miles was a British aviation engineer, socialite, and businesswoman. She was born into a well-known family of actors. She became interested in aviation in the 1920s, and married her flight instructor, Frederick George Miles. Together they eventually founded Miles Aircraft, where she was a draughtswoman and aircraft designer.
