Prof. MUDr. Jan Janský (Czech pronunciation: [ˈjan ˈjanskiː]) (April 3, 1873, Prague – September 8, 1921, Černošice near Prague) was a Czech serologist, neurologist and psychiatrist. He is credited with the first classification of blood into the four types (A, B, AB, O) of the ABO blood group system.

Janský studied medicine at Charles University in Prague. From 1899 he worked in a psychiatric clinic in Prague. In 1914 he was named professor. During World War I Janský served two years as a doctor at the front until a heart attack disabled him. After the war he worked as a neuropsychiatrist in a military Hospital (Vojenská nemocnice). He had angina pectoralis and died of ischaemic heart disease.

Janský was also a proponent of voluntary blood donations.

Through his psychiatric research, Janský tried to find a correlation between mental diseases and blood diseases. He found no such correlation existed and published a study, Hematologická studie u psychotiků (1907, Hematological study of psychotics), in which he classified blood into four groups I, II, III, IV. At the time this discovery passed almost unnoticed. In 1921 an American medical commission acknowledged Janský's classification (over that of Karl Landsteiner, who classified blood into only three groups; and was for this (blood types) discovery awarded the Nobel Prize in Physiology or Medicine in 1930). Janský's classification remains in use today. A similar classification was described by William Lorenzo Moss, except the I and IV of Moss were the opposite to that of Janský's, leading to confusion in blood transfusion until the use of A, B and O became standard.

Největší Čech (The Greatest Czech) is the Czech spin-off of the BBC Greatest Britons show; a television poll of the populace to name the greatest Czech in history. The series was broadcast by the national public-service broadcaster, Česká televize. The moderator of the programme was Marek Eben, who was also nominated to be in the Top 100; however, since he was moderating the show he was not eligible to be included in the final list.

The counting and ranking of the nomination votes took place during January 2005; the top 100 were announced on 5 May; and the final rankings were announced on 10 June 2005. Many voices received the fictional genius Jára Cimrman but he was disqualified.

At the same time as the nominations, an Internet vote for the greatest villain of Czech history was held. The top ten were:

The first round of official voting for Greatest Czech was won by the fictional character Jára Cimrman created by Czech humourists Jiří Šebánek, Zdeněk Svěrák (who himself took the 25th place) and Ladislav Smoljak (79th). The fact that he isn't a real person disqualified him from taking the title. Česká televize disregarded the rules, which clearly stated, that "it is only possible to vote for someone who was either born on, lived on, or in any way acted on the soil of Bohemia, Moravia or Czech Silesia." While Cimrman neither lived, nor was born in any of these countries, he indisputably acted (since 1966) and acts on the mentality of local people.
