To the best of my knowledge and belief, this essay contains the first appearance in print of the word chrononaut…. If an author allows his chrononauts to play an active part in the history of the age which they visit, he at once raises all sorts of problems.

Chrononaut is a word Ray has coined which means ‘time traveler’…. I've been training since my last trip in the Time Pool! I can stand up better to the battering and buffeting I'm getting. I'm becoming a regular ‘chrononaut’.

Addison addressed the Soviet chrononaut. ‘Officer N. Gauki…what in your mind is the greatest terror facing a time traveler? That there will be an implosion due to coincidence on re-entry, such as has occurred in our launch?

The Soviet chrononaut N. Gauki lifted both hands impassionedly and spoke to the Americans across the table from him in a voice of extreme urgency. ‘It is the opinion of myself and my colleague R. Plenya, who for his pioneering achievements in time travel has been certified a Hero of the Soviet People, and rightly so, that based on our own experience and on theoretical material developed both in your own academic circles and in the Soviet Academy of Sciences of the USSR, we believe that tempunaut A. Doug’s fears may be justified. And his deliberate destruction of himself and his team mates at re-entry, by hauling a huge mass of auto parts back with him from ETA, in violation of his orders, should be regarded as the act of a desperate man with no other means of escape.’

He had always handled himself well in front of crowds; that had been part of his training after he had been selected as the first chrononaut.

One of the earlier chrononauts turns up at the Mentnor’s [sic] house during a party and causes two deaths before destroying the Sphere.

Mr. Feghoot has not graced our pages in thirty-nine years—our time—but the chrononaut appears unchanged save for an odd bunch of pals he has brought with him.
