Summary
Analysis
John takes a cab to the cemetery where Dr. Hoenikker is buried, hoping to take a picture of the tomb (potentially as an image for the cover of his book). The cemetery custodian tells him that he can’t miss it: “the marker was an alabaster phallus twenty feet high and three feet thick.” John calls it “a suitable memorial to a father of the atom bomb.” Wiping away some sleet from the monument, John notices that it reads “MOTHER.”
The remarkable sight of the huge memorial speaks to humankind’s ability to celebrate or commiserate itself, here in an especially pompous way. Vonnegut flips it on its head by having the phallus commemorate Emily Hoenikker, not Frank.
