Retrieve highest value from sql table
===

How can retrieve that data:

    Name.....Title......Profit
    Peter    CEO........2
    Robert   A.D........3
    Michael  Vice.......5
    Peter    CEO........4
    Robert   Admin......5
    Robert   CEO........13
    Adrin    Promotion..8
    Michael  Vice.......21
    Peter    CEO........3
    Robert   Admin......15

to get this:

    Peter........4
    Robert.......15
    Michael......21
    Adrin........8

I want to get the highest profit value from each name. 
If there are multiple equal names always take the highest value.
