"Following the dark days of the Horus Heresy, when Space Marines fought fellow Space Marines and the whole Imperium was torn by conflict, the victorious commanders of the Emperor sat down together to draw up a new galactic order.... In particular, and after a great deal of discussion, they produced the great tome of ancient military wisdom known as the Codex Astartes.... Many of the most brilliant minds of the age contributed to the Codex Astartes.... With such brilliant minds as the Space Marine Primarchs Leman Russ and El'jonson offering sagely advice, as well as the practical wisdom of the great Imperial Guard commander General Tybour, the Codex Astartes has always been regarded as an essential part of every you officer's education." (Armies of the Imperium, p. 25)
Like I said he did not write it all. That quto came out alot later. Alot. In game and in real life. This one however comes from second edition of the game.

Who?
Many of the most brillent minds of the age.
To what?
The Codex Astartes.
"Ten thousand years ago, following the end of the Horus Heresy, the original Space Marine Legions were substantially reorganised to for the Space Marine Chapters we know today. A new code of organisation and operational methods called the Codex Astartes was drawn up by the Adeptus Terra. This sought to define standard organisations and uniform details as well as providing the ultimate reference work on strategy and tatics. Over the millennia most of the Chapters have evolved variations on the details laid down by the Codex Astartes. Some have changed quite radically so that their organisation and operating procdures bear almost no resumblance to the textbook. The Ultramarines however have retained every detail of the Codex Astartes intact and have become famous for their rigid adherance to its ancient orthodoxy." (Armies of the Imperium, p. 8)
Who made it?
A new code of organisation and operational methods called the Codex Astartes was drawn up by the Adeptus Terra.
He did not write ever word.
Think of it as the King James Bible. King James did not wite the bible. Yet he is given the Honour cause he paid for the project and decreed it to be.
Robert no doubt ask that it be made. Then all the military leaders surviving the Horus heresy put in their 2 cents. The the Scribes and peons bent back and started to compile it. Then it was off to the presses and poof you have a huge new book to be sent to each chapter master to help him in his duties.
And as I said flip through those Pages and you will find a ton of Leman Russ' quotes. because he contributed to it as well as countless others.
Which was my whole point. It is not a static book. And never was made to be one. It has blank pages for the chapter master to put down more words of wisdom as he aquires them. Even the one used by the Ultra Marines has adapted. Just not as often.
Which could be taken as of all the chapters of the Imperium the Ultra marines learn the least. lol If you think about it.
Now thou that is not true. Not with Nid hunters, and honour gaurds. They have become specialists too.
Which makes sence. If we do not learn from history we are doomed to make the same mistakes. So smarten up or die. Adapt and over come.
