The version history as it was included in PV-Ray 0.5 BETA. Notice the 
name changes...

Persistence of Vision Raytracer Version History
-------------------------------------------------

  PV-Ray was originally DKBTrace Ver. 2.12 written by David Buck. He
donated the rights to his source code so the PV-Team could enhance
this raytracer as a group project similar to Fractint. The source
code for PV-Ray will always be freely distributable subject to the
restrictions in the header files. Thanks David, for your generous
gift!
	
Version 0.02 BETA Release 7/29/91 (as STAR-Light)
----------------------------------
  First version is still basically DKBTrace 2.12 with a few new
  features.

  - Materials mapping added by Drew Wells.(see matmap.dat)
  - ONION & LEOPARD textures added by Scott Taylor.
  - Time to trace display added by Bill Pulver.
  - Grayscale display (+g) for IBM-PC's added by Scott Taylor.
  - Small wood texture bug fixed to create true cylinders.
  - Verbose now displays more info including file being traced.
  - Option +vO added to enable old-style terse verbose.
  - Texture.c broken into smaller modules.
  - PAINTED1, 2, & 3 added for developers.

Happy birthday POV-ray!
1991 was still the good old CompuServe days, before internet.

Cheers
Ton.

    Cambodia Civil War Ends,
    Free Elections in Taiwan,

That makes me feel old  :-)

I as 29 years old when we converted DKBTrace into POV-Ray.  I'd already 
been working on DKBTrace for about 6 years before then starting when I 
was around 23.  It's been a fun ride.

The software I wrote - Eureka 2.12 - is 34 years old in 2021, and
is named because of the version "2.12" of DKBTrace. Also Archimedes
died in 212 BC. I began to use POV-Ray in 1994, under SunOS. And I
ported some releases, when it was written in plain C language. What
you've done is really great. I'm so thankful to all this work :-)

Best regards,
