c# static class declaration

Programming in C#: c# static class declaration on newest questions tagged c# – Stack Overflow

Hi the intent of the code below is to return a static class which holds a related set of data. Can you recommend how I can do this better?

public class People
{
    //want info to be setup in this class, so it can be accessed elsewhere
    public static readonly string[] ab = { "ALBERT", "EINSTEIN"};
    public static readonly string[] dk = { "DONALD", "KNUTH" };

   //is this efficient or instantiated once per access? IF SO HOW CAN I DO THIS BETTER?
    public static readonly Info AB = new Info(ab, 100);
    public static readonly Info DK = new Info(dk, 80);

}

public class Info
{
    private string[] _name;
    private int _age;

    public string[] Name { get{ return _name}; }
    public int Age { get { return _age; } }

    public Info(string[] n, int a)
    {
        _name = n;
        _age = a;
    }
}
