I
wouldn't go so far as to call this doctor and scientist “Mr.
Urine,” but Carl Ludwig did develop the modern theory about the
formation of urine!
Ludwig
(who was born in Germany on this date in 1816) figured out that urine
was formed by a filtration process in the kidneys, and then he
modified his own theory to come up with the more complex
understanding of urine formation that still stands today.
But
there was a lot more to Ludwig's physiological contributions. He
invented ways to measure blood pressure and blood flow, he invented a
device to separate gases from blood, and he was the first to keep
animal organs alive outside the body. He even researched anesthesia.
He won numerous awards and is credited by scholars as having
contributed to our understanding of every body system other than our
sensory systems (sight, hearing, etc.).
But there's more. Ludwig was a professor and a great teacher. He founded a school: the Physiological Institute at the University of Leipzig.
And
of course you know what I'm going to say next:
There's
more. Way more. Ludwig (along with several others he discussed
science and medicine with in Berlin) rejected the idea that had
existed forever that biology had its own special laws and forces.
That living things were completely different from nonliving things in
their “vital force” – and that the physical and chemical laws
that applied in other scientific endeavors had no bearing on biology.
Instead,
Ludwig and his friends tried to understand the complexities of living
things by looking at those laws of physics and chemistry.
And
of course, they were right.
