Origin of The Term
The term datagram appeared first within the project CYCLADES, a packet switching network created in the early 1970s, and was coined by Louis Pouzin by combining the words data and telegram. CYCLADES was the first network to make the hosts responsible for the reliable delivery of data, rather than the network itself, using unreliable datagrams and associated end-to-end protocol mechanisms.
“The inspiration for datagrams had two sources. One was Donald Davies' studies. He had done some simulation of datagram networks, although he had not built any, and it looked technically viable. The second inspiration was I like things simple. I didn't see any real technical motivation to overlay two levels of end-to-end protocols. I thought one was enough.” —Louis Pouzin,These concepts were later adopted for the creation of the Internet Protocol (IP) and other (now deprecated) network protocols like e.g. AppleTalk or Xerox Network Systems.

In an old cellar hole in a byroad
The origin of all the family there.
Thence they were sprung, so numerous a tribe
That now not all the houses left in town
Made shift to shelter them without the help
Of here and there a tent in grove and orchard.”
