I didn't acknowledge someone who helped with my thesis, is there anything I can or should do now? I received help with some aspects of my PhD thesis from a tutor (proofreading and graphics). Of the help I received, some mathematical notation they provided made it into my thesis. 

However, I did not acknowledge the tutor in the PhD thesis for this help (since received). 

Is there anything I could (or should) do to rectify this?
If ever the thesis is published elsewhere, say as a paper in a journal or a conference, or perhaps as a technical report, include the name of the person there.
