how to remove the author in TwentyTwelve?

Do not edit the Twenty Twelve theme. It is will be the default theme in WordPress 3.5 and having access to an unedited version of the theme is vital when dealing with a range of site issues. First create a child theme for your changes.

Dear Esmi.

I’m struggeling with the same problem. I want to keep date and category but remove author. I created a child theme andf messed a little bit in the code. Everytime I remove an outhor part the whole line is missing. Pease help…

try to add this to style.css of the child theme:

.entry-meta .by-author {
	display: none;
}

remember to clear the browser cache after the changes to the css;

if that does not help, please post a link to your site to illustrate where the author information shows up.

I too am facing the same problem. My site TechToll every post has a about author information. I created a child theme and made `.entry-meta .by-author {
display: none;
}` but no change!

I even cleared the cache!

We’re happy to help with this, Techtoll.
