William James Sidis was a mind that arrived early and burned fiercely, a pioneer among pioneers, and his Sun in Aries tells that story from the first spark. Aries is the warrior at the front of the zodiac, the self-starter, the double leader who casts light and leaves a mark wherever it goes, and Sidis was first at almost everything. Raised by his psychiatrist father Boris under a deliberate programme to cultivate genius, he entered Harvard at eleven, was said to converse in some twenty-five languages, and later wrote The Animate and the Inanimate, published in 1925, speculating on the origins of life through the lens of thermodynamics. His contemporaries, among them Norbert Wiener and William James, agreed his intelligence was extraordinary. His Moon in Leo is the heart of the performer, king and queen at once, a psyche that feels through display and craves the warmth of recognition. Yet the fame that came so young curdled, and the very glare Leo hungers for became unbearable: he withdrew from public life, wrote under pseudonyms, and turned away from the mathematics that had made his name. A brilliant Aries flame that chose, in the end, its own quiet corner of the world, dying in 1944 at just forty-six.
