John Pilkington
Radio astronomer in the pulsar investigation
Also known as J. D. H. Pilkington
Who they are
John Pilkington contributed to the investigation of the pulsed radio signals first recognized by Jocelyn Bell Burnell. Her retrospective account credits him with measuring their dispersion, a frequency-dependent effect useful in assessing the signal’s journey through space. His role helps reveal the division of work within the pulsar-discovery team.
He shows how follow-up measurements helped evaluate whether an unexpected signal was astronomical.

Little Green Men, White Dwarfs or Pulsars?
Bell Burnell recounts identifying the repeating pulses and the subsequent checks by Hewish and other collaborators. Her retrospective separates telescope operation, recognition of the signal, timing analysis and independent checks.
Cosmic Search reprint, January 1979; the page identifies an earlier December 1977 publication as “Petit Four.”
Reading scope & citation
Freshly read the discovery narrative and publication note; historical recollection, not raw observing records. Reuses the input’s documented prior inspection: Discovery-sequence passages and reprint provenance inspected; account originated as a speech published December 1977. No fresh full-work reread in this directory pass. Existing discovery-sequence inspection reused; fresh page heading and provenance read. Original recordings and full 1968 discovery paper not audited.
