Word Origin:

Middle English patron ‘something serving as a model’, from Old French from Latin patronus ‘protector of clients, defender’, from pater, patr- ‘father’. The change in sense is from the idea of a patron giving an example to be copied. By 1700 patron ceased to be used of things, and the two forms became differentiated in sense.
