Johann Friedrich Julius Schmidt





Johann Friedrich Julius Schmidt

Born October 26, 1825                    Died February 7, 1884




The nineteenth century was a grand time to be a German in Athens. Even after local hard feelings had been assuaged by ridding King Othon’s government of his Bavarian advisors after 1843, German citizens still flocked to Athens, willing and able to help in the nation building process. And they were welcomed. It was mutually beneficial; German and Greek intellectuals were thinking along the same lines at the time. 

Greats such as Johann Winckelmann and Friedrich Schiller had already promoted adopting the values of ancient Greece as a pattern for their own country’s post-Enlightenment cultural progress.These were the very values that intellectuals in the new nation believed must underlie and define the cultural identity of the modern Greek state. (1)

So, while Heinrich Schliemann was busy uncovering the grave circles at Mycenae, a less well known German resident in Athens, was putting the finishing touches on his contribution to the glory of science. His name was Johann Friedrich Julius Schmidt: astronomer, geophysicist, and distinguished head of the National Observatory in Athens. He had just created a comprehensive map of the visible moon.

32,856 craters were identified and labeled on this map; it was four times more detailed than any lunar map hitherto attempted.

With today’s Hubble telescope, not to mention modern terrestrial ones, it is hard to appreciate the magnitude of this 19th century breakthrough. Schmidt still lived in an era when a smallish ocular telescope was the best you could hope for. Tenacity, keen eyesight, and a superior sensitivity to colour variation were as important prerequisites as the equipment in the observatory. He had these and spent his last 26 years studying the night sky from Athens.

The Observatory

Today’s residents, facing daily air pollution, might be surprised to learn that Athens’ once crystal clear skies were considered to be perfect for European star gazers. The proof is the impressive National Observatory of Athens (2), still perched on the Hill of the Nymphs opposite the Acropolis.




Now in the middle of the city, it was all alone when it was completed in 1846. And anyone who thinks scientists back then lacked a sense of flair or self promotion need to know that the laying of the corner stone in 1842 was timed to coincide with a total eclipse of the sun.

Its initial brief was to measure time and record meteorological phenomena. Its  final shape was a cooperative effort between its builders and the astronomers who planned to use it.

The original designer was another famous German Athenian, Eduard Shaubert. Although his original Byzantine cross shape remained, his design was modified by Theophil Hansen to conform to the severe neoclassical style so popular in Athens at the time.  

Hansen was so pleased with the result that he had Servare Intaminatum (To be Kept Intact) carved above the coat of arms of the Sinas family who had financed the project. 
  This admonition still greets the visitor today.



All distances from Athens to the rest of the world were measured from the Observatory’s foundations. With its prominent rounded dome (not to mentions its four arms pointing north, south, east, and west) it is tempting to regard the observatory as the post- Enlightenment omphalos of the new Greece!


But, back to our scientist.


The Man Who Put a Face on the Moon.

 Johann Friedrich Julius Schmidt was born in Eutin, Germany. His love affair with the moon began early. The story goes that, as a lad of 14, he steadied his first small telescope against a lamp post in order to view it more clearly.  His interest never waned...



He studied in Hamburg and  worked in observatories in Dusseldorf, East Prussia, Moravia, before moving on to Athens where he was appointed director of the Athens Observatory in 1858, a post he would hold until his death in 1884. 

Although the moon map is what he is most remembered for, he was also an expert in the study of comets, variable stars, sun spots, asteroids, as well as of terrestrial vulcanology.  He was, by all accounts, a true renaissance man of science - a meticulous workaholic, totally dedicated to uncovering the secrets of the known universe. He even discovered a new star (Q Cygnus).  His work was known and admired throughout Europe. A crater on the moon is still dedicated to his memory.

His reputation suffered a small eclipse of its own when he insisted that one of the craters on the moon was undergoing changes as he observed it – a proposition that was doubted even at the time. 


The Linné crater today, still  stubbornly refusing to alter

Science was younger then and, if he was wrong about the Sea of Serenity’s Linné crater, he would no doubt be delighted by recent discoveries of vulcanism on Io, one of the moons of Jupiter.

Schmidt remained active at the Observatory until his sudden and unexpected death on February 6, 1884.

His Death

 A day of mourning was announced and his funeral oratory, held inside the observatory itself, was attended by the King and Queen of Greece. He was buried in the Protestant section of the First Cemetery of Athens. It may not have been his choice had he not died so suddenly, but it is fortuitous for visitors like ourselves to be able to still read  his name, wonder,  and be reminded of yet another  small piece of Greek history.

The Grave


This grave lies beyond the impressive monument to George Finley in row F of the Protestant section. It is sadly neglected. Whether vandalism was intended or its condition is simple a result of the ravages of time, is hard to say. The moon, stars, and the tools of his trade are still clearly etched in marble:
