Etymology
the verb 'pasteurize' is a direct eponym, coined in the late 19th century to honor the pioneering work of louis pasteur. pasteur developed the process of partial sterilization, known as pasteurization, to combat spoilage in wine and beer, which was later famously applied to milk. the suffix '-ize', a productive verb-forming element meaning 'to render or make', was attached to his surname to create a term meaning 'to treat by the pasteur method'. thus, the word encapsulates a scientific breakthrough by memorializing its inventor within the language itself.
Analysis

pasteur (from french, a proper name, specifically louis pasteur, the french chemist and microbiologist) + ize (from greek -izein via latin -izare and french -iser, a suffix forming verbs meaning 'to make, to treat in a specific way').
Examples
