Bill McDonagh
From BioShock Wiki
Bill McDonagh speaks with a Cockney accent and served as the general contractor in Rapture under Andrew Ryan. A well meaning man who believed in the promise of Rapture, he provided the expertise and labor necessary to build Rapture. They met while McDonagh was repairing the fixtures in Ryan's bathroom. Ryan asked why McDonagh was using brass fixtures instead of the tin ones that were arranged with the contractor. He replied that he would pick up the cost of the fixtures, as a point of personal pride being that none of his work had ever leaked. Impressed, Ryan made him general contractor. He displayed a more realistic outlook than Ryan, realizing that things were getting out of control and that real grievances did exist among Fontaine's followers, due in strong part to the excesses and philosophy of Ryan himself. Ken Levine stated that he used characters as themes in BioShock, with Bill McDonagh representing Ryan's conscience.
According to There's Something in the Sea, Bill McDonagh's disappearance from the surface was noticed by his nephew Flann McDonagh.
As McDonagh grew more and more aware of Ryan's megalomania, realizing that a plasmid "arms race" was brewing, he objected to Ryan nationalizing Fontaine Futuristics, and pleaded with him to hand it over to Atlas as a peace offering. But only to be ignored. Bill McDonagh is found killed and impaled on a pillar outside of Andrew Ryan's office in Rapture Central control, after having turned on Ryan in an attempt to prevent the chaos from growing worse.
