Dud Dudley was the first to make a successful attempt to extract iron from its ores by means of pit-coal, it having till 

 then been produced by the far more expensive charcoal ; and thus immensely lessening its cost. 



Although Sturtevaut's and Rovenson's methods proved failures, their works are nevertheless important as having 

 stimulated Dud Dudley in his own discovery. ,
