then just put it Person

eg,

class Person
  def self.add_accessor accessor_name
    self.class_eval %Q{
    attr_accessor :#{accessor_name}
    }
  end
end
#=> nil

person=Person.new
#=> #<Person:0x871188c>

Person.add_accessor :name
#=> nil

Person.add_accessor :gender
#=> nil

person.name="Peter Cooper"
#=> "Peter Cooper"

person.gender="male"
#=> "male"

person.name
#=> "Peter Cooper"

person.gender
#=> "male"
