Toblerone was created by Theodor Tobler and Emil Baumann in Bern, Switzerland in 1908. The two gentlemen developed a unique milk chocolate including nougat, almonds and honey with a distinctive triangular shape. The product's name is a portmanteau combining Tobler's name with the Italian word torrone (a type of nougat). The image of a bear is hidden in the Matterhorn mountain symbolizing the town of its origin.
Theodor Tobler applied for a patent for the Toblerone manufacturing process in Bern in 1906. The Toblerone brand was trademarked in 1909, at the Federal Institute for Intellectual Property in Bern. Albert Einstein was employed there as a patent clerk at the time.
In 1932 Tobler made the first filled bars of chocolate, the Tobler-O-rum.
Since the 1970s, other versions of the Toblerone have been produced. These include plain chocolate (dark chocolate) in a green or black wrapper, white chocolate in a white wrapper, "snow-capped" editions with white chocolate peaks (also in a white/silver wrapper), Filled editions - milk chocolate with a white chocolate centre (blue wrapper), and OneByOne, individually wrapped triangular chunks. New for 2007 is a Fruit and Nut version with a half purple cardboard box. New for 2008 is a Honeycomb crisp version with a half white box with honeycomb pieces pictured on it. Bar sizes range from ten centimetres to nearly one metre, all similarly proportioned.
