Michael Saul Dell was born on February 23, 1965, in Houston, Texas, into a Jewish family. His father, Alexander Dell, was an orthodontist, and his mother, Lorraine Charlotte (née Langfan), was a stockbroker. His family’s original surname, “Thal” (meaning “valley”), was Anglicized when his ancestors immigrated to the United States. Early on, Dell displayed remarkable business instincts: as a child he purchased a calculator, disassembled an Apple II at age 15 to explore how it worked, and even applied to take a high-school equivalency exam at age eight. During high school he sold newspaper subscriptions in creative ways, earning substantial income. He enrolled at the University of Texas at Austin as a pre-med student in 1983, but his entrepreneurial activities soon overtook his schooling.
