Making the American Body by Jonathan Black

In Making the American Body, journalist Jonathan Black explores the history of health and fitness from aerobics to Zumba. Promotion of physical fitness goes back to the founding of the United States; Black notes that Benjamin Franklin praised the use of dumbbells. Franklin was known to be a fan of swimming, too. It began to gain some momentum in the middle 1800s when German immigrants brought the gymnasium (they called it a Turnverein) to the U.S.

I was draw to the book because it has a touch of Missouriana in the person of Bernarr Macfadden, self-proclaimed “Father of Physical Culture.” Macfadden had a classic story of the early bodybuilder. He was a sick, weak kid from the Ozarks who was transformed into a paragon of masculine pulchritude by his commitment to weight training, healthy eating and clean living. Unlike some of his contemporaries, Macfadden believed clean living included an active sex life and he campaigned against prudery. His magazines, headed by Physical Culture, featured photographs of nearly naked men and women in swimsuits.

Fitness promotion is a small world, and many of its leading figures are connected. Macfadden organized a contest (probably fixed) that crowned Charles Atlas the “World’s Most Beautiful Man.” Atlas’ ads in pulp magazines and comic books are probably some of the most well-known ever, especially the bully of the beach ad. The story of this ad, told in comics form, is based on a real event in Atlas’ life when he was shamed by a muscular life guard for his scrawny form and weakness while on a date at the beach.

Macfadden and many others were inspired by Prussian strongman Sandow. They saw him at the Chicago Columbian Exposition, where his show was produced by Florenz Ziegfeld, Jr.

California became a focus of health and fitness trend that would spread across the country. Santa Monica’s Muscle Beach was a place for weight lifters and gymnasts to have fun and show off. Steve Reeves, known for playing Hercules in several films, was a product of Muscle Beach. Jack LaLanne, another wimpy kid transformed, opened gyms, brought workouts to television, and encouraged women to exercise and do strength training.

Other trends gained popularity, especially fitness focused on cardiovascular health. This brought into popular culture Dr. Kenneth Cooper, a physician to astronauts whose 1968 book Aerobics launched an industry. That industry provided a career for Richard Simmons and a second career for Jane Fonda, who was the first to emphasize exercise as a way for women to lose weight (though this was an unspoken appeal long before the 1970s). Bodybuilding made a comeback, though, especially fueled by the popularity of Arnold Schwarzenegger.

I’m not especially interested in the health and fitness industry, but I found this book to be very interesting. It provides a historical context for many of the health and fitness trends that are still part of American culture.

Miss Leavitt's Stars by George Johnson

The universe has grown a lot in the last century, at least in the estimation of astronomers. A series of observations, discoveries, and estimations have led from a view that the entirety of the universe is a smallish Milky Way galaxy to the present view in which many galaxies, and large clusters of galaxies, occupy a space that is billions of miles across.

One of the early, and still much used, discoveries that made measuring the universe possible was the period-luminosity relationship of a set of variable stars called Cepheids. Variable stars change in brightness over times. Cepheids change in brightness with a regular pattern. The length of that pattern, or period, is related to the average brightness of the star. Brightness and distance are hard to measure; the star appears brighter or dimmer based on how near or far away it is. Measuring the period of a Cepheid lets us know its brightness, and comparing that to its apparent brightness lets us know how far away it is (using a relationship called the inverse square law).

The Cepheid period-luminosity relationship was discovered by Henrietta Swan Leavitt. She was not recognized as a professional astronomer by the  academic leaders of Harvard University, where she worked, even though she had academic credentials and publications that put her on par with many who had doctorates in the field.

She was a woman and she was a computer. Before the invention of modern electronic computers, computers were people who managed data and performed calculations. Little is known about how Leavitt felt about the sexual discrimination that was common at the time, and she seemed to be contented with her life. Even so, if she had been a man, her accomplishments would very likely have earned her a plum appointment.

George Johnson’s book about this accomplished woman, Miss Leavitt’s Stars, is not a book about discrimination. It is a brief biography of a little-known astronomer who laid the groundwork for our understanding of the size of the universe.

Leavitt, who died relatively young, left a legacy in the science built on her work. Some of that appears in the work of famous Missourian Edwin Hubble, namesake of the Hubble Space Telescope, used Leavitt’s period-luminosity law to estimate the distance to Andromeda, and determine that it must be separate galaxy and not a cloud in the Milky Way. Astronomy has advanced a lot in the last 90 years, but astronomers continue to use Leavitt’s work to estimate distances in space when they can find Cepheids.

Johnson’s book is short. This is partly because Levitt didn’t leave much of a paper trail outside of her professional writing. It is about equal parts popular science and biography. I enjoyed it, yet I can imagine it being within the grasp of a high school student. It may be a good book for a budding astronomer or physicists. Unfortunately, there may not much more that we can learn about Leavitt, but her story is an introduction to Hubble, Einstein, and others who did important work relevant to astronomy.
