Harold Waldorf

Harold Waldorf is Blair Waldorf's father and Eleanor Waldorf- Rose's first husband. He ran off to Paris with one of Eleanor's male models, Roman. He is played by John Shea.

Harold Waldorf is Blair's absent father, although he seems to care very much about her welfare, Blair clearly favours her father over her mother and idolises him, wanting to go to his alma mater, Yale. Since he lives in Europe with his partner Roman, Blair rarely gets to see her father, and sometimes resents Roman for taking him away from her.

Harold is often seen during holidays such as Thanksgiving and Christmas, where he and Blair have traditions that she loves. Although she initially resents Roman's presence in them, she warms up to him and later seems to accept his place in her father's life.

Harold also appears in season 2 when it seems clear that Blair will get admitted to Yale. When she expelled for spreading rumours about Mrs. Rachel Carr and Dan Humphrey he fights for her and is disappointed when he finds out that she's been lying all along.

Nevertheless, he and Blair maintain a very strong bond. Harold is always the first to be there for Blair although he finds that difficult when she is always scheming and he is round the globe from her.
