Bonkers was developed from Liberty and Delicious by Cornell University at the famous New York Agriculture Experiment Station at Geneva, where it was known as NY35. Although samples were sent to nurseries the variety was never officially released.  It was named "Bonkers" by organic apple enthusiast Michael Phillips, who had obtained samples from Cummins Nursery, and was impressed by the flavors and organic productivity.
