John Knibb (1650-1722) was the younger brother of Joseph (1640-1721) to whom he was apprenticed in Oxford in about 1664. At the age of twenty, when Joseph left for London, John took charge of the Oxford business, and in 1673 upon payment of a fine he received the Freedom of the City.
There are far fewer extant table clocks signed John Knibb than those signed Joseph Knibb. There have been may opinons expressed that John may have helped Joseph's London workshops. The comparatively small output of Oxford clocks and the fact that John had no fewer than ten apprentices might suggest that much of the workshop's energy went towards working for Joseph.
