I read Vice Admiral George Emery’s insightful piece (“An Admiral’s Letters to His Son,” October, pp. 50–53) with mixed feelings. The article initially conveyed a feeling of poignancy in seeing a sensitive side of Admiral Hyman Rickover, whose reputation for demanding, spartan leadership in founding our nuclear Navy was unmatched. That he carved out time for frequent, meaningful letters to his only child despite a nearly inhuman workload was commendable parenting. But as a former surface line communications and security officer, my secondary reaction was one of chagrin at the admiral’s apparent disregard for the handling of what might have been highly classified information on the capabilities and performance of our new nuclear ships.
