Bernauli Family-

Naughty but Brilliant.


    


Jacob Bernouli (1654 - 1705) 
Johann Bernouli (1667 - 1748)
Daniel Bernoulli (1700 - 1787)

Nicholas Bernoulli migrated from Holland to Switzerland during the 18th Century. 

They were being chased by the Catholics.


                               

  Popular Discovery:-Bernouli Principle. This helped to design aircraft wings.        


Born to a prosperous family of traders and scholars from the city of Basel in Switzerland, 

Against the wishes of their father to take over the family business or to enter respectable professions like medicine or the ministry, and began studying mathematics together.They had other siblings too.

Birth

1654

1667

Graduated from the University of Basel with a master's degree in philosophy.

 

1676.  Age 22Yrs.

A licentiate in theology.

 

During this time he studied Mathematics and Astronomy against the wishes of his parents.

1683 Age 16Yrs.

Failing in the spice trade entered the University at the and studied medicine. He did not enjoy medicine and learned mathematics from his elder brother Jacob.  

In two years John learned everything Jacob knew.

 

 

Graduated from Basel University,

Personal; biography

They developed a rather jealous and competitive relationship.

 

1681 Age 27Yrs.

He travelled to the Netherlands where he met many mathematicians including Hudde. Continuing his studies with the leading mathematicians and scientists of Europe In England he met Boyle and Hooke.

 

1684 Age 30Yrs.

He married Judith Stupanus.

It was case of teacher-pupil quarrel. The two brothers vehemently fought for superiority. Two of them competed for the University chair and the elder one won it by chance.

 

1694  Age 27Yrs.

He married Dorothea Falkner.

John left the country, saying he would never return...

 

1705  Age 38Yrs.

When his father in law requested to see his daughter and the grand children he had to concede.  

 

He was jealous of the elder Jacob's position as professor at Basel 

 

Johann published a book based on his son’s work, even changing the date to make it look as though his book had been published before his son's.

Contribution

Both had a clear aptitude for mathematics at a high level, and constantly challenged and inspired each other. They established an early correspondence with Gottfried Leibniz, and were among the first mathematicians to not only study and understand infinitesimal calculus but to apply it to various problems.

 

 

His book “The Art of Conjecture”, published posthumously consolidated existing knowledge on probability theory and expected values,

 

His theory of permutations and combinations, Bernoulli trials,

Bernoulli distribution, and number theory, such as the Bernoulli Numbers sequence.

 

He became the first person to develop the technique for solving separable differential equations His method of describing the location of points in space using angles and distances and was the first to use the word “integral” to refer to the area under a curve.

 

Employment

1676  Age 22Yrs.

After taking his theology degree, he moved to Geneva where he worked as a tutor.

He then travelled to France spending two years studying with the followers of Descartes 

1683 Age 29Yrs.

Taught mechanics at the University in Basel.

1694 Age 27Yrs.

He accepted a post as the professor of mathematics at the University of Groningen in Netherland.

 

While he was traveling back to Basel his brother died of tuberculosis.

So he took his chair.

 

 

 

Progeny/ Students

Two children, a son who was given his grandfather's name of Nicolaus and a daughter.

A pupil-  Leonhard Euler 

Three sons that became brilliant mathematicians.

Nicolaus II. Daniel & Johann II.

Death

1705 Age 51Yrs.

1748  Age 81Yrs.

 

 

His student Guillaume de l'Hôpital published a book in his own name consisting almost entirely of Johann's lectures, including his now famous rule about 0 ÷ 0 (a problem which had dogged mathematicians since Brahmagupta's initial work on the rules for dealing with zero back in the 7th Century).

 

Three sons of Johann Bernauli.
