According to [http://research.microsoft.com/users/lamport/pubs/pubs.html#chandy Leslie Lamport's website], the snapshot algorithm was described when they visited Chandy, who was at the [[University of Texas (Austin)|University of Texas (Austin)]]. He posed the problem over dinner, but they had too much wine to think about it. The next morning, while they were in the shower, they came up with the solution. When theyLamport arrived at Chandy's office, he was waiting for her with the same solution. They considered the algorithm to be the straightfoward application from the basic ideas of article 27, titled "'''Time, Clocks and the Ordering of Events in a Distributed System".''' <ref>{{Cite web |title=The Writings of Leslie Lamport |url=https://lamport.azurewebsites.net/pubs/pubs.html?from=https://research.microsoft.com/users/lamport/pubs/pubs.html&type=path#time-clocks |access-date=2024-08-24 |website=lamport.azurewebsites.net}}</ref>
