 ## Early computing (1940s - 1950s)
 
 **Mainframes and Early Computing:** The first "datacenters" didn't exist in the modern sense, but large mainframe computers were housed in controlled environments to handle data processing. These mainframes were typically stored in research facilities or corporate locations.
-- In the 1940s, the concept of data center was developed by J. Presper Eckert and John Mauchly. Eckert and Mauchly were the primary inventors of the ENIAC computer, which was the world's first data center, built in 1946 at the University of Pennsylvania in the US.  However, the ENIAC was very different from the data centers we have today.
