Women in Science 2016: Elsa Garmire

Women’s History Month began yesterday. This year, I would like to highlight the achievements of a number of amazing women whose work may not be known to the general public, but who are doing, or have done, important research. I won’t limit myself to the field of optics, but I shall start with it.

Elsa Garmire is currently a professor of engineering at Dartmouth College up in New Hampshire. She has had a five-decades-long career in physics, which included a year of service as OSA’s 1993 President (the second of five women to hold that position over the past century).

Garmire was only one of two students to earn her Ph.D. under Charles H. Townes during his stint at MIT in the mid-1960s. Obviously, women in physics were few and far between in those days, more so than now. However, Townes had four daughters of his own and realized that young women were perfectly capable of studying science. Plus, Maria Goeppert-Mayer received the Nobel Prize in physics the year before Townes did.

Once Garmire became a postdoctoral fellow out in California, though, she wasn’t taken as seriously as a scientist as she might have been. And she was living in the trippy, groovy era of the Sixties. So she explored her artistic side and ended up playing a major role in the creation of laser light shows [PDF].

Eventually, she became a professor at the University of Southern California before moving to Dartmouth. After a successful career in lasers and nonlinear optics, she has decided to retire this year. I wish her well and hope that she will continue to stay in touch with OSA.

The centennial of Charles Townes

Today, July 28, would have been the 100th birthday of Charles H. Townes. Of course, he’s not here to enjoy it, because he passed away six months ago.

Optics & Photonics News marked the centennial by tweeting a link to the feature article I wrote about Dr. Townes for the May 2015 issue. The Charles Townes Center, a program for gifted students in his hometown of Greenville, S.C., posted a birthday remembrance on its Facebook page. A German website posted this message (in German) about Dr. Townes’ contributions to astronomy. And tonight the South Carolina State Museum will have special programs in honor of the state’s native son. From the museum’s website:

DID YOU KNOW? July 28th would have been the 100th birthday of laser pioneer and Nobel Prize winner Charles Townes. Townes, who passed away in January of this year, was a South Carolina native who won the Nobel Prize for his inventions of the laser and maser and helped build the foundation of laser technology.  Museum educators will be discussing his revolutionary work from 6 – 8 p.m. in front of the Townes exhibit, which houses his Nobel Prize among other laser-related artifacts.  At 7 p.m., experience the technology that Townes developed in Laser Fun, a 40-minute planetarium laser light show set to an assortment of family-friendly songs. In addition, from 7 – 8 p.m., author Rachel Haynie will be signing copies of her children’s book, “First, You Explore: The Story of the Young Charles Townes.” Activities are included with general admission, however there is an additional fee to see the planetarium laser light show.

Townes Symposium planned for October

Personal reminisces of Charles H. Townes’ long career are on the agenda of a special symposium that will take place at Frontiers in Optics/Laser Science 2015. Several of Townes’ past students from Columbia, MIT and Berkeley will share their memories, and other speakers will discuss his later-in-life contributions to astronomy and to projects such as the Townes Laser Institute at the University of Central Florida.

The organizer of the symposium is Elsa Garmire, who served as OSA’s second female president. If you are interested in her career, you can read about some of her early work in “A Short History of Laser Light Shows” — which is, perhaps, the only magazine article ever to mention both Charles Townes and Pete Townshend.

My article on Charles Townes

As I mentioned earlier this year, I was working on an OPN article about Charles H. Townes, one of the most important scientists of the 20th century, when he passed away. My article came out in the May issue of OPN, which is traditionally about lasers because of the annual CLEO conference. It made the cover of the magazine, so the editorial staff made it “open access” for everybody!

CLEO, by the way, is next week in San Jose, California. I wish I could attend, but it’s not in this year’s cards. The conference program sounds awesome — you can’t beat plenary lectures by two Nobel Prize winners. There’s no memorial symposium for Dr. Townes, as far as I can tell, but such things take time to organize; I’ll bet one will be held sometime in the next 12 months.

Charles Hard Townes, 1915-2015

Yesterday I awoke to the news that Charles Hard Townes, a 1964 Nobel laureate for fundamental work on maser and laser physics, had died on Tuesday, January 27. In six months and a day, he would have turned 100 years old, but you can still think of this as his centennial year, in my opinion.

During my years working at OSA, I met six Nobel Prize winners; five are still with us. But Dr. Townes always looked hale and hearty, even well into his 90s, and he always went to conferences with his beloved wife, Frances — I thought that was so sweet of them. He was always the gentleman and not the least bit overbearing. At the symposium on the exact 50th anniversary of the first laser, when Dr. Townes gave his talk on the history of laser physics, he took a red laser pointer out of his pocket and used it so matter-of-factly, without harping on the fact that it — and a huge amount of today’s optical technology — has its roots in the insight he once had on a humble park bench just a few blocks from the White House.

I was already planning to write an article about Dr. Townes for an upcoming issue of OPN, so his death adds a new poignancy. I have to get back to work now, so I’ll leave you with a few links to some of the obituaries that have come out.

What I’ve been up to

November is almost half over, so if you have access to Optics & Photonics News, please hop on over to my feature article on the 150th anniversary of the U.S. National Academy of Sciences (NAS) and learn something new about this venerable institution.

The OPN editor assigned me this feature; I didn’t dream it up myself. At first, I worried that I would be able to connect NAS to OSA and the world of optics and photonics in only the most vague and general way, and I would leave my readers scratching their heads and wondering, “Why the heck is this in my magazine?”

Fortunately, just around the time I started my background research for this article, the NAS held a historical symposium at Woods Hole in Massachusetts. While listening to the live webcast, I learned that three of OSA’s most famous Honorary Members — George Ellery Hale, A.A. Michelson, and Robert A. Millikan — had played significant leadership roles within the Academy at various times in its existence. Hale, a solar physicist and observatory impresario, spurred the NAS to start publishing a Proceedings journal and served as the first chair of the National Research Council (NRC); Michelson, the first American Nobel physics laureate, served a term as NAS president in the 1920s, when the Academy opened its first headquarters building in Washington, D.C.; and Millikan, first to measure the electric charge of the electron, edited the Proceedings through the 1940s. Those connections helped me frame the story and make the history of the NAS relevant to today’s optical scientists. (After all, who hasn’t had to recreate either the Michelson-Morley speed-of-light experiment or the Millikan oil-drop experiment, or both, in undergraduate physics classes?)

In between my longer articles for OPN, I have been writing some short pieces as well: on a superfast quantum light switch, improved detection of high-frequency UV light, and a compound that can hide from infrared cameras at some temperatures.

Finally, back in April I mentioned that I had a “day job” working for some sort of educational center that hadn’t yet opened, but I didn’t get into details. However, now that the parent institution has started to advertise it, I can do The Big Reveal!

One month from today, the Smithsonian’s National Museum of Natural History will open Q?rius, a new hands-on learning center for ages 10 and up. I wrote a series of REALLY short (i.e., one-paragraph) essays about geological specimens that will reside in the Q?rius collection. Other museum staff members have been developing novel interactive experiments and demonstrations covering all aspects of the research going on at the museum. I can hardly wait for Q?rius to open, and I hope to see you all there!

It’s been 50 years now…

Dear Nobel Committee for Physics at the Swedish Academy of Sciences:

I realize, of course, that by now you have probably already made your decision about this year’s Nobel Prize in Physics. After all, the award is scheduled to be announced on October 8, which is a mere three weeks from today. Obviously it takes some time to prepare the gold medals and certificates and whatnot, and to write up the press release extolling the achievements of the winners — I’m using the plural here, because you choose more than one laureate in the vast majority of years. And I know you try assiduously to uphold the original intent of Alfred Nobel’s will.

This year marks the 50th anniversary of all the events that happened in 1963, from the good (the “I Have a Dream” speech, the early stages of Beatlemania) to the bad (the 16th Street Baptist Church bombing, the JFK assassination). The event that’s relevant to this discussion is the 50th anniversary of the awarding of the Nobel Prize in physics to Maria Goeppert-Mayer (along with two male scientists) for her work on nuclear shell structure.

In other words, this year makes 50 years since a woman received a Nobel in physics. Chemistry and medicine/physiology have had several female laureates in the past half-century — from Dorothy Hodgkin to Carol Greider — but not physics. There have been women who were mysteriously left out (Jocelyn Bell Burnell, Chien-Shiung Wu) and at least one female physicist who won the medicine Nobel (Rosalyn Yalow).

I’m certainly not recommending that a woman get a Nobel in physics just because of her gender — duh! However, every year the world has at least a few more female physicists than the year before, and some of them, somewhere, must have done some Nobel-quality research by now. Please recognize her (or them). Please don’t wait another half-century to name a third physics laureate.

Sincerely yours,

A concerned female holder of a B.S. in physics
