“Great Bernoulli family Swiss
To math never gave a miss
And 'twas always a fight
As to who had the right
To publish which, what and this."


(Quoted from Mathematics From the Birth of Number, Jan Guilberg)


The Bernoulli family produced nine outstanding mathematicians / physicists in three generations. If you ever wondered if mathematical genius is passed on through your genes from your family, or if it is learned, this is one story that seems to show that at least a good part of it really is in your genetic code. The family also produced many other very successful members in law, scholarship, science, literature, and the arts. None were failures. Strangely, as the mathematical ability was handed down generation after generation, it seems most of them tried to avoid being mathematicians! 

Having so many geniuses in the family can be hazardous to family relationships. Competitiveness among even father and son created problems between family members striving for recognition in an age when having the right to claim an idea was a marker of success and even financial prosperity.

"...it would be better for the true physics if there were no mathematicians on earth."        Daniel Bernoulli, quoted in The Mathematical Intelligencer (1991).

Daniel Bernoulli is known for having discovered and developed Bernoulli's Principle, which states that as the speed of a moving fluid increases, the pressure within the fluid decreases. This is the principle that all aviation engineering is based upon.
