== Description in lead paragraph == 

 I've corrected the description of Wright in the lead paragraph.  Although Wright used actuarial tables in his pioneering insurance work, he was not a pioneer in the theory or construction of the tables themselves.  I also clarified that the "father" appellation is used only in the United States.  I doubt very much that British or German actuaries consider Wright to be the "father" of their insurance industries (but if I'm wrong about this, please let me know).
