The French theologian Jean Calvin (1509-1564) and the philosophers Jean-Jacques Rousseau (1712-1778) and Jean-Paul Sartre (1905-1980) are well-known bearers of this name. It was also borne by the German-French Dadaist artist Jean Arp (1886-1966).
This name has been used in Britain since the Middle Ages. It has been especially popular in Wales, where it is used in honour of the 5th-century patron saint of Wales (also called Dewi), as well as in Scotland, where it was borne by two kings. Over the last century it has been one of the English-speaking world's most consistently popular names, never leaving the top 30 names for boys in the United States, and reaching the top rank in England and Wales during the 1950s and 60s. In Spain it was the most popular name for boys during the 1970s and 80s.
Famous bearers include empiricist philosopher David Hume (1711-1776), explorer David Livingstone (1813-1873), musician David Bowie (1947-2016), and soccer player David Beckham (1975-). This is also the name of the hero of Charles Dickens' semi-autobiographical novel David Copperfield (1850).
The popularity of the name in continental Europe was due to the fame of Charles the Great (742-814), commonly known as Charlemagne, a king of the Franks who came to rule over most of Europe. His grandfather Charles Martel had also been a noted leader of the Franks. It was subsequently the name of several Holy Roman emperors, as well as rulers of France, Spain, Portugal, Sweden and Hungary (in various spellings). After Charlemagne, his name was adopted as a word meaning "king" in many Eastern European languages, for example Czech král, Hungarian király, Russian король (korol), and Turkish kral.
The name did not become common in Britain until the 17th century when it was borne by the Stuart king Charles I. It had been introduced into the Stuart royal family by Mary Queen of Scots, who had been raised in France. Two other kings of the United Kingdom have borne this name, including the current monarch.
Other famous bearers include naturalist Charles Darwin (1809-1882) who revolutionized biology with his theory of evolution, novelist Charles Dickens (1812-1870) who wrote such works as Great Expectations and A Tale of Two Cities, French statesman Charles de Gaulle (1890-1970), and American cartoonist Charles Schulz (1922-2000), the creator of the Peanuts comic strip.
According to Genesis in the Old Testament Adam was created from the earth by God (there is a word play on Hebrew אֲדָמָה (ʾaḏama) meaning "earth"). He and Eve were supposedly the first humans, living happily in the Garden of Eden until they ate the forbidden fruit from the tree of knowledge of good and evil. As a result they were expelled from Eden to the lands to the east, where they gave birth to the second generation, including Cain, Abel and Seth.
As an English Christian name, Adam has been common since the Middle Ages, and it received a boost after the Protestant Reformation. A famous bearer was Scottish economist Adam Smith (1723-1790).
As an English name, Aaron has been in use since the Protestant Reformation. This name was borne by the American politician Aaron Burr (1756-1836), notable for killing Alexander Hamilton in a duel.
