Here's a short story:

Popper is known for his rejection of the classical inductivist views on the scientific method, in favour of empirical falsification: A theory in the empirical sciences can never be proven, but it can be falsified, meaning that it can and should be scrutinized by decisive experiments. He used the black swan fallacy to discuss falsification. If the outcome of an experiment contradicts the theory, one should refrain from ad hoc manoeuvres that evade the contradiction merely by making it less falsifiable. Popper is also known for his opposition to the classical justificationist account of knowledge, which he replaced with critical rationalism, "the first non-justificational philosophy of criticism in the history of philosophy." 

Karl Popper was born in Vienna (then in Austria-Hungary) in 1902, to upper middle-class parents. All of Karl Popper's grandparents were Jewish, but the Popper family converted to Lutheranism before Karl was born, and so he received Lutheran baptism. They understood this as part of their cultural assimilation, not as an expression of devout belief. Karl's father Simon Siegmund Carl Popper was a lawyer from Bohemia and a doctor of law at the Vienna University, and mother Jenny Schiff was of Silesian and Hungarian descent. After establishing themselves in Vienna, the Poppers made a rapid social climb in Viennese society: Simon Siegmund Carl became a partner in the law firm of Vienna's liberal Burgomaster Herr Grübl and, after Grübl's death in 1898, Simon took over the business. (Malachi Hacohen records that Herr Grübl's first name was Raimund, after which Karl received his middle name. Popper himself, in his autobiography, erroneously recalls that Herr Grübl's first name was Carl.) His father was a bibliophile who had 12,000–14,000 volumes in his personal library. Popper inherited both the library and the disposition from him. (End of story)
