When Charles Hard Townes stepped up to the podium at ICALEO® in September 2010, he was a 95-year-old legend speaking to hundreds of disciples whose life’s work stemmed from his creations.

It was his own life’s work that brought him to Anaheim that year to accept LIA’s first Lifetime Achievement Award.

“It was an amazing address,” recalls Tom Kugler, fiber systems manager for Laser Mechanisms. “Here was a tall but rather frail-looking man who moved rather slowly up to the podium and then turns to the audience and brings forth a booming voice — strong and sure. He had great stories; the one I remember most was that (Niels) Bohr thought that his ideas regarding the physics of the maser were wrong. Niels Bohr, father of the atom! What Townes wanted us to know is that you have to persevere, no matter who the detractors are, if you know that the science is right.”

Townes, professor emeritus of physics at the University of California, Berkeley (read their appreciation here), persevered to the point where he still made daily visits to the campus up until about a year before his death Tuesday in Oakland. The man who created the maser and conceived the laser discussed his thoughts on receiving his LIA honor in a May 2010 email from his Berkeley account.

“I am very privileged to receive the lifetime achievement award,” he said. “And I feel my life has been very privileged by the opportunity to do research, discover new things, and particularly by the discovery of how a laser could be made. I am also delighted by the many contributions that colleagues have made in development of the laser and further associated discoveries. These have made the field of optics blossom with so many fascinating contributions to science and to technology. Many thanks for this honor, and more importantly many thanks for the many contributions other scientists and engineers have made towards the exciting growth of optics.”

As his New York Times obituary notes, Townes and his brother-in-law, Arthur L. Schawlow, secured a patent for their “optical maser” through Bell Laboratories in 1959 — a year before Theodore Maiman built the first operational laser.

In a video celebrating the Nobel Prize-winning inventor around the time of his 99th birthday (he shared the 1964 prize in physics with Russians Nicolay Basov and Aleksandr Prokhorov), Townes joked that his time on campus “isn’t work; this is just fun. I’ve been practically never working all my life. I always have fun doing physics.”

He often told the tale of the revelation — occurring as he sat on a park bench in Washington, D.C. — that led to his ground-breaking invention. In an interview during the celebration of the 50th anniversary of the laser, he recalled wondering why he hadn’t been able to come up with an idea for how to produce short waves while doing spectroscopy in the microwave region with electronic oscillators. Before the last meeting of a national committee he was heading up to study the problem, “I pulled out an envelope from my pocket and wrote down the equation” that proved to be the answer. Instead of unveiling what he called “kind of a funny idea” at the meeting, he waited until he got home and fleshed out the roadmap for what became the maser (microwave amplification by stimulated emission of radiation).

For his efforts, LIA “decided to present the special award to professor Townes to recognize his contribution to the development of the first laser 50 years ago and in recognition of his lifetime body of work,” said LIA Executive Director Peter Baker. It was “a huge privilege” to listen to Townes’ presentation, which he remembered included the pioneer’s story of how two Nobel-winning professors senior to him tried to dissuade him from continuing his early research.

While we mourn the passing of this giant and his legacy, we fondly recall his passion and vigor and thank him for the work that continues to guide our mission.
