Roberts

"This is a private party, young man. I cannot allow you in."

- Roberts

Roberts served as the doorman at the cocktail party for Marshall College faculty and administration staff in 1936. The slim balding man answered the door when Alec Sutherland tried to enter. Overhearing Sutherland call for him, Indiana Jones let Roberts know that he would talk to the uninvited guest, and the doorman permitted Sutherland to come in.

Behind the scenes
Because the location for the cocktail party is not known, it is not clear whether Roberts was an employee of the college, or just a servant employed by the party venue's owner. It is clear that Jones knows Roberts' name.
