There were a bunch of Bernoullis. Daniel Bernoulli is the guy in this
case.

Family of Swiss mathematicians and scientists, including Jakob or
Jacques (1654=961705), an important developer of ordinary calculus and the
calculus of variations. His brother Johann or Jean (1667=961748) developed
the calculus of variations. Johann's son Daniel (1700=961782) anticipated
the law of conservation of energy, did pioneering work in the molecular
theory of gases, and contributed to probability theory and the theory
of differential equations.


Venturi:

Main Entry: ven=B7tu=B7ri
Pronunciation: ven-'tur-E
Function: noun
Etymology: G. B. Venturi died 1822 Italian physicist
Date: 1887
: a short tube with a tapering constriction in the middle that causes an
increase in the velocity of flow of a fluid and a corresponding decrease in
fluid pressure and that is used especially in measuring fluid flow or for
creating a suction (as for driving aircraft instruments or drawing fuel
into the flow stream of a carburetor)

Henri Pitot's invention was almost 100 years earlier, and Ventura CA
was founded in 1782.
