Jara Cimrman (Czech: Jára Cimrman), also known as "The Master", a fictional character, is presented as a universal genius and one of the greatest Czech playwrights, poets, composers, teachers, travellers, philosophers, inventors, detectives, mathematicians and sportsmen of the 19th and early 20th centuries. He was born between 1853 and 1884 (or 1889) in Vienna. He died in 1914 in Liptakov, or after 1918 in Frymburk, or in 1921 in the area of Kokorin, or perhaps at another time and place.

Two of 136 possible depictions of Jara Cimrman - the inventor of the round stamp. The stamps were officially issued by the Czech Post.
As an inventor, Cimrman had many important inventions to his credit, but their patenting always narrowly escaped him and the inventions were attributed to others. Many times he contributed to the solution or influenced the final shape of the work of more famous colleagues: the Marconi wireless telegraph, the layout of the elements in Mendeleev's table, the shape of the Eiffel Tower, etc. His inventions include the two-piece swimsuit, yoghurt, the web, the CD (Cimrman's disk). When Alexander Graham Bell invented the telephone, he found three missed calls from Jara Cimrman upon making his first connection.
The Jara Cimrman Theatre, founded by Jiri Sebanek, Zdenak Sverak (Czech: Jiří Šebánek, Zdeněk Svěrák) and Ladislav Smoljak, processes the Master's fictional life and work. To this day, it still performs plays attributed to Jara Cimrman and is one of the most visited theatre houses in Prague. On 16 September 2016, the theatre celebrated fifty years since the first play by Jara Cimrman was staged.

On this day, the Master's silhouette appeared on Google Doodles along with a number of his ingenious inventions.
Introduced by Czech authors in the 1960s, Jara Cimrman has since gained immense popularity in Czech culture. In 2005, he won a public vote to find The Greatest Czech, although his fictional nature prevented him from actually winning. Many streets in the Czech Republic have been named in his honour, as well as waterfronts, squares, schools, lookout towers and museums. Many plaques and statues have been dedicated to his memory. His name has also entered zoology and botany. By naming a dark Adeonian asteroid 7796 Jaracimrman his fame has rightly reached the universe :-)
