John Adelbert Davis (August 7, 1871 – March 17, 1934) was the founder of the Practical Bible Training School in Johnson City, New York, in 1900.
Davis conducted meetings in the following years of his life all over the east coast of the United States including: Binghamton, Baltimore, Maryland, Brooklyn, and New York.
In the summer of 1900, the classes of the Practical Bible Training School began in Lestershire (now Johnson City), New York.
Davis chose a long-time friend John R. Clements to be the first president of the college.
The next year in 1932, several faculty and staff left to form Baptist Bible Seminary (now in Clark Summit, Pennsylvania).
