Abstract
H. L. Johnson, 1964, BOTT, 3, 25, 305 established standard stars for his JKL and M photometry, and developed a calibration that enabled him to determine bolometric corrections and effective temperatures. In many ways Johnson anticipated the developments that were about to come forth. Many of Johnson's observations of the bright stars might still be the best available because astronomy has concentrated heavily on fainter objects following the end of Johnson's career.
