"Fascinating.... You may already have your dream lover, but you'll want to read this for the many insights on the science of love."--The Boston Globe

"Why Him? Why Her? examines how brain chemistry determines temperament and temperament dictates whom we love.... [Fisher offers] a giddy, romantic notion, well worth considering."--Los Angeles Times

"In times of upheaval, nothing offers safe harbor like science. That's where Helen Fisher comes in.... Her research led her inside the biological mechanisms of mate choice."--TIME magazine

Praise for Helen Fisher:

"Fascinating.... An original and uniquely contemporary approach to a sensation that, for millennia, has been considered purely emotional." --The Washington Post on "Why We Love"

Dr. Helen Fisher, referred to by Time magazine as “the queen mum of romance research,” is an internationally renowned biological anthropologist and one of the world’s leading experts in the science of human attraction. Using functional magnetic resonance imaging, she studies the brain in love. And with her long-standing research, she helped develop one of the fastest-growing online relationship sites, Chemistry.com, a subsidiary of Match.com. Introduced in February 2006, Chemistry.com features the Chemistry Personality Test and Matching System, both developed by Fisher. To date, more than seven million people have taken the test, which is available in forty countries. In addition to serving as the chief scientific adviser for Chemistry.com, Fisher has authored several books and many articles in scientific journals and popular magazines. Her perspective on love, sexuality, women, and gender differences is regularly featured in major news outlets, including The Today Show, CNN, National Public Radio, BBC, and The New York Times. As a research professor in the Department of Anthropology at Rutgers University, she focuses on the role of biology in human sex, love, and marriage.

Fisher’s widely anticipated book Why Him? Why Her? (Henry Holt and Company; January 20, 2009) proves her scientific hypotheses about why we are attracted to one person rather than another. Why Him? Why Her? follows Fisher’s 2004 book, Why We Love (Henry Holt), which was translated into sixteen languages. It discussed her research on the brain physiology, evolution, and worldwide expression of romantic love. In her 1999 book, The First Sex: The Natural Talents of Women and How They Are Changing the World―which received the New York Times Book Review Notable Book award and was published in fourteen languages―she discussed gender differences in the brain and behavior, and the impact of women on twenty-first-century business, sex, and family life. Fisher’s other books include Anatomy of Love: The Natural History of Mating, Marriage, and Why We Stray (1992), also a New York Times Notable Book, with nineteen foreign-language editions; and The Sex Contract: The Evolution of Human Behavior (1982), translated into five languages. Her articles have appeared in The Journal of Comparative Neurology, Journal of Neurophysiology, Archives of Sexual Behavior, Journal of Sex and Marital Therapy, The Journal of NIH Research, Psychology Today, Natural History, New Scientist, The New York Review of Books, The Chronicle of Higher Education, and many other journals, magazines, and books.
