Exceedingly rare TLS signed “Stephen,” one page, 8 x 9.75, University of Cambridge, Department of Applied Mathematics and Theoretical Physics letterhead, November 10, 1970. Letter to physicist Charles W. Misner, a professor at the University of Maryland, in full: "A student of mine, Gary Gibbons, will be attending the A.P.S. meeting in New Orleans from November 23rd to 25th, where he will report on the British work on the design and construction of gravitational wave detectors. We think that, without the use of liquid helium, we can improve the sensitivity by a factor of 100. The first of these detectors should be operating before the end of the year, and the second one at Reading should follow soon after.

As he is getting his fare paid to New Orleans I thought that Gary might as well stay on and attend the relativistic astrophysics meeting Austin. I asked Howard Laster to write to Weber to try and arrange for Gary to visit Maryland for a few days after the New Orleans meeting. Weber replied that he was very busy and would not be able to devote more than a very short time to showing Gary round. However, although Gary has devoted quite a time to the design of gravitational wave detectors, he is primarily a theoretician and is interested in the problem of how much gravitational radiation would be emitted by a collapsing object. He would very much like to have an opportunity to discuss this with you and Brill. I wonder, therefore, if you could possibly arrange for Gary to spend several days at Maryland and reassure Weber that he will not have to devote all his time to him.

We have now got a little girl who was born last Monday. Her name is registered as Catherine Lucy, though we will probably call her Lucy. She looks quite like Robert did when he was born but she is a bit plumper. She is very well behaved and causes very little trouble. Give my regards to Susanne and the children. Hope to see you in Austin." In fine condition, with some light creasing.

A remarkable letter in which Hawking writes about the hunt for gravitational waves (finally detected in 2016), asks his correspondent to aid his doctoral student Gary Gibbons (today an accomplished theoretical physicist), and announces the birth of his daughter (Catherine Lucy, who indeed goes by Lucy today).

One hundred years after Albert Einstein first predicted the existence of gravitational waves, scientists finally received proof of these disturbances in the curvature of spacetime: the ‘ringdown’ following the collision of two black holes was detected at the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) and announced on February 11, 2016. When asked for comment, Stephen Hawking said that the discovery would ‘revolutionize’ astronomy, noting also that proved his calculations made in 1970—the same year he wrote this letter—to be correct: ‘The observed properties of this system are consistent with predictions about black holes that I made in 1970 here in Cambridge.’

He goes on to ask Dr. Misner to aid his doctoral student, Gary Gibbons, during his trip to America. Hawking and Gibbons would go on to collaborate in their research, lending their names to the ‘Gibbons-Hawking effect,’ ‘Gibbons–Hawking space,’ ‘Gibbons-Hawking ansatz,’ and ‘Gibbons–Hawking–York boundary term.’ For his contributions to General Relativity and the Quantum Theory of Gravity, Gibbons was elected a Fellow of the Royal Society in 1999.

Hawking also mentions his one-year old daughter, Lucy, his second child, who had been born on November 2, 1969. Today, she is a science educator and writer, and co-author of five cosmos-related children’s books with her famous father.

Diagnosed with early-onset motor neurone disease in 1963, Hawking’s physical capabilities deteriorated over time—his shaky hand evinced in this signature of seven years later—making authentic autographs exceedingly scarce. Confined to a wheelchair by the end of the 1970s, he opted to sign with just a thumbprint later in life. As an incredibly rare autograph from one of the towering scientific figures of the 20th century, with profound scientific and personal content, this is a truly spectacular letter.
