Father Figures in Fiction

It has occurred to me that many of the books I really enjoy feature central male roles that could be considered to be 'father figures'. They are rarely true fathers - I have struggled to find many fictional fathers that possess the characteristics I have in  mind (Atticus Finch in To Kill a Mockingbird is a rare example). Most fathers in fiction seem to be either bullies (eg. Michael Henchard in The Mayor of Casterbridge) or weaklings (eg. Mr Bennet in Pride and Prejudice). I am thinking of male characters that are dependable, intelligent and trustworthy, and always win through despite the odds.

These father figures are rarely glamorous. Take, for example, Mick Herron's Jackson Lamb. He is the slob of Slough House, and yet you can be certain that he will get his team out of all of their spying scrapes. Le Carre's George Smiley is a portly plodder, but he is meticulous, and his convoluted plans trap the traitor, and eventually the traitor's boss.
Romance doesn't figure prominently in the lives of these characters. It may not be mentioned at all (eg. Jackon Lamb), or it is unsuccessful (Smiley), or in the background, as with Madame Maigret in Simenon's novels.
I think Jules Maigret typifies my idea of a good 'father figure': he cares for his wife and his colleagues, and even his clients. He is physically strong, yet generally gentle. He is observant and thoughtful. He always solves the crime.
My father figures are taken from the world of crime and espionage, but there must be many others. What about Gandalf?! Suggestions welcome.
