The formula on his tombstone, S = k log W, is the equation for the entropy of a system of particles. It states that entropy, which can be regarded as a measure of a system’s “disorder,” depends only on a constant number k (now named Boltzmann’s constant) and the number of possible “microstates” W. Microstates essentially describe the configurations of the locations and momenta of particles in a system.
In 1904 Boltzmann visited the World’s Fair in St Louis, USA. He lectured on applied mathematics and then went on to visit Berkeley and Stanford. Unfortunately he failed to realise that the new discoveries concerning radiation that he learnt about on this visit were about to prove his theories correct.
At sixty-two, suffering from incumbent blindness and other ailments, in the process of giving in to depression after the loss of his eldest son, his pride and self-esteem took a great toll owing to the criticism of many fellow scientists. Boltzmann then sought refuge and peace of mind in the small village of Duino, on the border of the Astro-Hungarian Empire. Neither the sunsets non the beautiful gulf nor Rilke’s verses helped him fend off the terrible depression that was devouring his soul and on a bleak day towards the end of the summer, on September 5th 1906 Boltzmann took his life by hanging himself from the window of his hotel room – formerly known as Hotel Ples now the one of the buildings of the United World College, opposite the Carabinieri station.

Simmeringer Hauptstraße 234, Vienna,
Grave Location:Gruppe 14 C, Grab Nr. 1
Grave Location Description
As you enter the cemetery through Tor 2 (Gate 2) drive straight ahead towards The St. Charles Borromeo Cemetery Church in the middle of the Vienna Central Cemetery. As you approach the church take the second to last right turn before the church and look to your left into Gruppa 14 C and you will find the large, unmistakable memorial to one of the greatest theoretical physicists of all time Ludwig Boltzmann.

popular name: Pierre Curie
date_of_death: April 19, 1906
cause_of_death: Accidental - Slipped while crossing street and a heavy horse-drawn cart wheel ran over his head
best_know_for: Pierre Curie was a French physicist, a pioneer in crystallography, magnetism, piezoelectricity, and radioactivity. In 1903, he received the Nobel Prize in Physics with his wife, Marie Curie, and Henri Becquerel.
Jean Baptiste Perrin
popular name: Jean Baptiste Perrin
date_of_death: April 17, 1942
cause_of_death: Natural Causes
best_know_for: Jean Baptiste Perrin was a French physicist who, in his studies of the Brownian motion of minute particles suspended in liquids, verified Albert Einstein’s explanation of this phenomenon and thereby confirmed the atomic nature of matter (sedimentation equilibrium). He was awarded with the Nobel Prize for Physics in 1926 for this achievement.
Sir Isaac Newton
popular name: Sir Isaac Newton
date_of_death: March 28, 1727
cause_of_death: Experienced severe pain in his abdomen and blacked out, never regained consciousness, and died the next day
best_know_for: Isaac Newton was an English mathematician, physicist, astronomer, and theologian, is considered one of the great figures in the history of math and science. His ideas about motion and gravity are fundamental to the science of physics and other fields. He discovered calculus, proposed new theory of light and color, advanced early modern chemistry, and invented the reflecting telescope. His highly influential books include "Philosophiæ Naturalis Principia Mathematica" (Mathematical Principles of Natural Philosophy) on classical mechanics, "Opticks" on theories of light.
