Acknowledgements section of master's thesis Besides thanking my thesis advisor, can I acknowledge other professors who have guided me along the way during my master's program or is the acknowledgements section really only for thanking the advisor?
You might want to peek at a few other examples to make sure there's no institutional norms, but you can often acknowledge whoever you want, and indeed its a good place to acknowledge more personal contributions.

For example, in mine I acknowledge:


My advisor
The other members of my committee
Some colleagues who provided data
A family member who used to be a member of a profession who I asked a few questions about
Several fellow students
My funding sources
StackOverflow and CrossValidated
My favorite purveyor of caffeine.
