Birdsall Holly Broadbent Sr. (27 September 1894 – 23 December 1977) was an American orthodontist who is credited with developing and introducing the technique of cephalometric roentgenography to orthodontics.
[1] He also devised the cephalometer, which accurately positions a patient's head with reference to the x-ray source.
During the 1933 World Fair in Chicago Broadbent displayed the results of his study of facial development which he took from a series of cephalometric records that he took from his patients.
This longitudinal study which consisted of cephalometric measurements had 3500 school children aging from birth to adulthood.
