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.
What religion did Popper's family observe during his youth?
Lutheranism

Cytokinins are a class of plant hormones named for their control of cell division or cytokinesis. The natural cytokinin zeatin was discovered in corn, Zea mays, and is a derivative of the purine adenine. Zeatin is produced in roots and transported to shoots in the xylem where it promotes cell division, bud development, and the greening of chloroplasts. The gibberelins, such as Gibberelic acid are diterpenes synthesised from acetyl CoA via the mevalonate pathway. They are involved in the promotion of germination and dormancy-breaking in seeds, in regulation of plant height by controlling stem elongation and the control of flowering. Abscisic acid (ABA) occurs in all land plants except liverworts, and is synthesised from carotenoids in the chloroplasts and other plastids. It inhibits cell division, promotes seed maturation, and dormancy, and promotes stomatal closure. It was so named because it was originally thought to control abscission. Ethylene is a gaseous hormone that is produced in all higher plant tissues from methionine. It is now known to be the hormone that stimulates or regulates fruit ripening and abscission, and it, or the synthetic growth regulator ethephon which is rapidly metabolised to produce ethylene, are used on industrial scale to promote ripening of cotton, pineapples and other climacteric crops.
What are cytokinins responsible for in plants?
control of cell division

Bermudians served in the British armed forces during both World War I and World War II. After the latter, Major-General Glyn Charles Anglim Gilbert, Bermuda's highest-ranking soldier, was instrumental in developing the Bermuda Regiment. A number of other Bermudians and their descendants had preceded him into senior ranks, including Bahamian-born Admiral Lord Gambier, and Bermudian-born Royal Marines Brigadier Harvey. When promoted to Brigadier at age 39, following his wounding at the Anzio landings, Harvey became the youngest-ever Royal Marine Brigadier. The Cenotaph in front of the Cabinet Building (in Hamilton) was erected in tribute to Bermuda's Great War dead (the tribute was later extended to Bermuda's Second World War dead) and is the site of the annual Remembrance Day commemoration.
Who was the youngest Royal Marine Brigadier?
Brigadier Harvey
