Company history
Iron Mountain traces its origins to 1951, when Herman Knaust converted a former iron-ore mine into a secure storage facility and founded Iron Mountain Atomic Storage. Its first customer, East River Savings Bank, deposited records there that August.[29] C. Richard Reese took over in 1981 and led a period of expansion. Iron Mountain went public in 1996 and completed its acquisition of records-storage competitor Pierce Leahy in 2000.[30][31][32]
William Meaney became chief executive in 2013. Iron Mountain elected real estate investment trust status effective in 2014, then completed its acquisition of records-management company Recall in 2016. In 2017, it announced an agreement to acquire IO Data Centers’ U.S. operations, marking a significant expansion of its data-center business.[33][34][35][36] [29][30][31][32][33][34][35][36][29][30][31][32][33][34][35][36]
