Radium ( /ˈreɪdiəm/ RAY-dee-əm) is a chemical element with atomic number 88, represented by the symbol Ra. Radium is an almost pure-white alkaline earth metal, but it readily oxidizes on exposure to air, becoming black in color. All isotopes of radium are highly radioactive, with the most stable isotope being radium-226, which has a half-life of 1601 years and decays into radon gas. Because of such instability, radium is luminescent, glowing a faint blue.

Radium, in the form of radium chloride, was discovered by Marie Skłodowska-Curie and Pierre Curie in 1898. They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later. Radium was isolated in its metallic state by Marie Curie and André-Louis Debierne through the electrolysis of radium chloride in 1910. Since its discovery, it has given names like radium A and radium C₂ to several isotopes of other elements that are decay products of radium-226.

In nature, radium is found in uranium ores in trace amounts as small as a seventh of a gram per ton of uraninite. Radium is not necessary for living organisms, and adverse health effects are likely when it is incorporated into biochemical processes because of its radioactivity and chemical reactivity.

Leonard George DeStoppelaire (January 5, 1923 – February 12, 2006), better known as Lenny Dee, was a virtuoso organist who played many styles of music. His record albums were among the most popular of easy listening and space age pop organists of the 1950s through the early 1970s. His signature hit, Plantation Boogie, charted as a Top 20 hit in 1955. He also had a gold record with 1970's Spinning Wheel.

Dee played a variety of songs in numerous styles. He played original compositions, popular songs, and novelty tunes, and was a master of improvisation. Although his unique style was a pop/boogie-woogie blend, he also played ballads, country and western, jazz, rock, and patriotic songs.

Born in Chicago, Illinois in 1923, Dee was an only child (though it is sometimes erroneously reported that he was one of eleven or twelve children). As a child, he sang in his church's choir; he also played ukulele and accordion. As a teenager, he turned playing the accordion into a profession, which he continued until he was drafted into the Navy during World War II in 1943.

Marie Skłodowska-Curie (7 November 1867 – 4 July 1934) was a French-Polish physicist and chemist famous for her pioneering research on radioactivity. She was the first person honored with two Nobel Prizes—in physics and chemistry. She was the first female professor at the University of Paris, and in 1995 became the first woman to be entombed on her own merits in the Panthéon in Paris.

She was born Maria Salomea Skłodowska ([ˈmarja salɔˈmɛa skwɔˈdɔfska]) in Warsaw, in what was then the Kingdom of Poland. She studied at Warsaw's clandestine Floating University and began her practical scientific training in Warsaw. In 1891, aged 24, she followed her older sister Bronisława to study in Paris, where she earned her higher degrees and conducted her subsequent scientific work. She shared her 1903 Nobel Prize in Physics with her husband Pierre Curie and with the physicist Henri Becquerel. Her daughter Irène Joliot-Curie and son-in-law, Frédéric Joliot-Curie, would similarly share a Nobel Prize. She was the sole winner of the 1911 Nobel Prize in Chemistry. Skłodowska-Curie was the first woman to win a Nobel Prize, the only woman to date to win in two fields, and the only person to win in multiple sciences.
