Spaceman Garrard is the third pilot to attempt the trip to the binary star system of Alpha Centauri using the FTL drive invented by Dolph Haertel (the next Einstein!) The Haertel Complex stories provide little in the way of actual time travel, but this one does have minor relativistic time dilation and more significant differing time rates. —Michael Main

Blish’s story “Beep” appeared in 1954 with a casual mention of time-travel when a message is overheard from a future spaceship that’s following a worldline backward through time. The main story follows video reporter Dana Lje who stumbles upon the newly invented Dirac radio which allows instantaneous communication and, as only she realizes, also carries a record of every transmission ever made, both past and future.

At Larry Shaw’s request, Blish expanded “Beep” into the short novel The Quincunx of Time, and both these stories share a background wherein the work of Dolph Haertel (the next Einstein) provides an FTL-drive (the Haertel Overdrive, later called the Imaginary Drive), an antigravity device (the spindizzy), and an instantaneous communicator (the Dirac Radio). I read many of these in the early ’70s, but can’t find my notes and don’t remember any other time travel beyond that one communiqué that Lje overheard. Still, I’ll list everything in The Haertel Scholium and reread them some day!

I bought the first four of these collections in July of 1971 in Huntsville, and the rest I snapped up as they were issued in the ’70s (plus Blish’s original novel Spock Must Die!). At that point in my life, I could recite them by heart. Here’s the list of time-travel adaptations, which does not include “The Naked Time” (in Star Trek 1) since the 71 hours of time travel was omitted in the Blish version:
