Egbert Dearborn is the elder brother of Sam Dearborn.  He was to be appointed head of the Department of Magical Law Inforcement at the Ministry of Magic proceeding the resignation of Alex Potter.  However, due to his plans about disallowing rights for Muggle-borns being leaked, a protest against him was staged by the organization Magic for Peace.  As a result of the protest, Dearborn's harsh reactions to it, and some quick penning by reporter Rita Skeeter, Bartemius Crouch ended up with the job instead.
