## Summary

A 2004 C&EN feature marking the 50th anniversary of the first synthetic diamond synthesis, examining the contested credit story among GE's Project Superpressure team members including Hall, Bundy, Strong, and Wentorf. Published by the American Chemical Society's flagship news publication.

## Useful Claims

- The first reproducible synthetic diamond synthesis occurred on December 16, 1954, at General Electric.
- H. Tracy Hall's Belt apparatus was the device used in the successful synthesis.
- Credit for the first synthesis is historically contested among Project Superpressure team members.
- GE announced the achievement publicly in February 1955.
- The scientific and priority disputes among Hall, Bundy, Strong, and Wentorf remain unresolved in the literature.

## Reliability Notes

C&EN is a peer-reviewed/editorially rigorous publication of the American Chemical Society; this article is a strong secondary source for the contested-credit narrative and timeline. It is a retrospective piece (written 50 years after the events), so primary GE laboratory notebooks and patent records should be consulted for definitive attribution.
