Leland McCauley III was a wealthy industrialist in the 30th Century who became business rivals with R.J. Brande. This made him an antagonist to the Legion of Super-Heroes. McCauley passed this legacy on to his son Leland McCauley IV who became an even greater enemy to the Legion. In Reboot Legion continuity, Leland McCauley funded a rival team to the Legion known as Workforce. Eventually he was killed by Ra's al Ghul who assumed his identity. There has also been a Leland McCauley seen active in the 21st Century as a mentor to Azrael and a member of the Order of Purity. Leland McCauley was created by Jim Shooter and Win Mortimer, first appearing in Adventure Comics #374. (1968)
