Who was Boz?

The pseudonym that Charles Dickens used to write these first sketches of daily life in early Victorian London, Boz, apparently came from the way Charles's younger brother, Augustus, pronounced the nickname the writer had given him: Moses. Dickens had taken the name from a character in Oliver Goldsmith's The Vicar of Wakefield and his younger brother could only pronounce it through the nose. Therefore, Moses became Boses and Boses was shortened to Boz.
After I finish reading this delightful collection of impressions of life in Victorian England, I think I will buy this DVD, and possibly the book too. '''''''''''''''''' (This was Michi, agreeing with me, while he tried to open the bottle of brewer's yeast pills. He's addicted to them!).
