Shirley Marie Tilghman, FRS (née Caldwell; born 17 September 1946) is a Canadian scholar in molecular biology and an academic administrator, the President of Princeton University. She is the first woman to hold the position and only the second female president in the Ivy League. A leader in the field of molecular biology, Tilghman was a member of the Princeton faculty for 15 years before being named president.

Tilghman graduated from Kelvin High School in Winnipeg, Manitoba and received her Honours B.Sc. in chemistry from Queen's University in Kingston, Ontario, in 1968. After two years of secondary school teaching in Sierra Leone, West Africa, she obtained her Ph.D. in biochemistry from Temple University in Philadelphia, Pennsylvania under Richard W. Hanson.

She married Joseph Tilghman in 1970. This marriage ended in the early 1980s, leaving Tilghman with custody of their young daughter (Rebecca) and infant son (Alex). She attributes her successful balancing of a scientific career and caring for her family to organization and focus. Her goal was to not feel guilty while at work or at home, instead focusing on the task at hand.

Jeffrey Preston "Jeff" Bezos (/beɪzəs/, born January 12, 1964) is an American entrepreneur who played a key role in the growth of e-commerce as the founder and chief executive officer of Amazon.com, Inc., an online merchant of books and later of a wide variety of products. Under his guidance, Amazon.com became the largest retailer on the World Wide Web and the model for Internet sales.

Bezos was born Jeffrey Preston Jorgensen in Albuquerque, New Mexico, to Jacklyn Gise Jorgensen and Ted Jorgensen. His maternal ancestors were settlers who lived in Texas, and over the generations acquired a 25,000 acre (101 km² or 39 miles²) ranch in Cotulla. Bezos' maternal grandfather was a regional director of the U.S. Atomic Energy Commission in Albuquerque. He retired early to the ranch, where Bezos spent many summers as a youth, working with him. At an early age, Bezos displayed a striking mechanical aptitude – as a toddler, he tried dismantling his crib with a screwdriver.

Bezos was born to a teenage mother in Albuquerque. Her marriage to his father lasted little more than a year. When Jeff was five, she remarried, this time to Miguel Bezos. Miguel was born in Cuba, immigrated to the United States alone when he was fifteen years old, worked his way through the University of Albuquerque, married, and legally adopted Jeff. After the marriage, the family moved to Houston, Texas, and Miguel became an engineer for Exxon. The young Bezos attended River Oaks Elementary School in Houston from fourth to sixth grade. As a child, he spent summers at his grandfather's ranch in southern Texas, "laying pipe, vaccinating cattle and fixing windmills."
