Who's famous defensive chess players?

I'm interested in famous chess players who cherish rigid defense more than offense.
Please tell me who are there.

Petrosian, most notably.

Ulf Andersson.

Spassky , Petrosian and Steinitz , the first official world champion.

To add to these, Hort was said to be difficult to beat. Karpov is also - like Petrosian - famous for his prophylactic chess, even in situations where he has the initiative.

I agree with @Fates2 on Steinitz, Spassky and Petrosian.

I would add Capablanca. Watch out how he destroyed marshall gambit for the first time + first or second game against Lasker on the world champion match + with his match against alhekine that was far superior in opening preparation to kill capablanca it took him a match of 34 games to beat Capablanca

If you want to have a look of Steinitz you can look at Steinitz chigorin were you have lots of evan's gambit and sometimes Steinitz wins or loses ... but how he holds everything with Qf6 which is a bad move is very impressive.

Ps: I know some games by spassky and Petrosian and I know they are very solid player but I have not yet seen their wolrd champion matches

Karjakin.

Guys thank you for telling me.
"Petrosian" is might be interesting.
I didn't know the guy "Petrosian".

But, I think Kasparov likes dynamic variations and aggressive styles.

@Idasca
Not Kasparov, Karpov

@TheLostRaiderDude
I don't know "Karpov".
The names are so confusing between them.
