1955 Doc Brown with Brain Wave Analyzer.
Complete with head wound from failing off the toilet which then leaded to him inventing the flux capacitor.
In 1955 when Marty is stranded in the past he arrives as Docs House and is greeted by 1955 Doc, who then proceeds to try and read his mind to no avail.
