I’m looking for examples of the most famous and/or successful sibling rivalries. Also, let’s stick to rivalries that were self-created, i.e. due to dislike/hatred for one another or siblings just being competitive. For example, we would exclude athletes who were forced to play against one another due to being on opposing teams or in the same competition.
In the world of business, I can think of 2 off the top of my head:
The Dassler brothers who founded Adidas, and then had a falling out after which one of the brothers founded Puma.
More recently, the Ambani brothers, who are the world’s richest sibling billionaires. They can’t stand each other but still live in the same mansion in Mumbai.
The feud between Oscar-winning actresses Olivia de Havilland and Joan Fontaine is legendary. They apparently never got along, were jealous of each other’s Hollywood success, and haven’t spoken in 40 years.
The joke is neither will die until the other does first - both women are currently in their mid-90’s.
Dear Abby and Ann Landers. (They were twins, too.) Ann started her column, and then Abby started one, and they were rivals for a very long time. IIRC, they made up eventually.
In which area/field are they successful rivals? Sure, Oasis was a huge success but that was due to the brothers working together and not as rivals. And not getting along is not a prerequisite, although it is often the source of a successful rivalry. In retrospect, I should have asked for “famous and successful” examples in lieu of “famous and/or successful”.
How about the other Gallagher brothres, the comedians? The Gallagher (Leo) took his brother (Ron) to court for impersonating his act. Leo won, and the most interesting thing to come from it was that Ron is prohibited from “intentionally bearing likeness to his brother.”
From history, I have to imagine the de Medicis must have had at least one falling out. Same with all the Rothschilds. Did the Rockefellers have any falling outs?
Not exactly a rivalry, but Bill and Charlie Bidwill were joint owners of the Chicago/St. Louis Cardinals after the death of their father and mother. They tried to run the team jointly for ten years. Finally, Bill bought Charlie out, and Charlie went on to be a big name in horse racing.
