The chroniclers, ethnohistorians, and linguists of the Ohlone population began with: Alfred L. Kroeber who researched the California natives and authored a few publications on the Ohlone from 1904 to 1910, and C. Hart Merriam who researched the Ohlone in detail from 1902 to 1929. This was followed by John P. Harrington who researched the Ohlone languages from 1921 to 1939, and other aspects of Ohlone culture, leaving volumes of field notes at his death. Other research was added by Robert Cartier, Madison S. Beeler, and Sherburne F. Cook, to name a few. In many cases, the Ohlone names they used vary in spelling, translation and tribal boundaries, depending on the source. Each tried to chronicle and interpret this complex society and language(s) before the pieces vanished.
