The name Bob is a diminutive form of the name Robert, which has its origins in the Germanic languages. The name Robert is derived from the old Germanic roots "hrod" and "berht," which together mean "bright fame" or "bright renown." The name was brought to England by the Normans after their conquest in 1066 and quickly became a popular name among the nobility and royalty.

One of the earliest recorded instances of the name Bob can be found in the 14th century writings of Geoffrey Chaucer, where the character Bob is referred to in his famous work, "The Canterbury Tales." This suggests that the diminutive form of Robert was already in use by that time.
