Things that looked strange and didn't survive

This investigation began with several apparently sharp discontinuities in the transistor chronology. Some became much less impressive when the direct notebooks, units and wartime process record were checked. Keeping these failures visible is one of the safeguards against turning an audit into an anomaly-collection machine.

The sudden two-point geometry

A compressed story can make December 15–16 look like a jump from one-contact surface experiments straight to the successful split-gold pair. Direct December 4 notebook material already contains close two-point configurations and explicitly considers using one point to modulate current associated with another. The remaining provenance question moves earlier; the dramatic one-day topology miracle does not survive.

The factor-of-ten spacing discrepancy

A secondary numerical claim of 4×10⁻⁴ cm suggested a contact separation around 4 micrometres, dramatically smaller than the familiar few-mil scale. A closer source audit supports 4×10⁻³ cm—about 40 micrometres—as the relevant reading in the historical reconstruction. The apparent factor-of-ten anomaly was a transcription/source problem.

The mysteriously advanced germanium

Suitable high-back-voltage germanium looked more anomalous before the wartime Bell lineage was reconstructed. Scaff and Theuerer's 1945-priority process describes exactly the kind of purification, controlled impurities, n-type high-back-voltage material and point-contact rectifier practice that later transistor work could inherit. The exact December sample lineage still matters, but general material capability is not unexplained.

The >100 microsecond lifetime requirement

This was a potentially dramatic physics claim: perhaps the first transistor required minority-carrier lifetimes only achieved later with better-grown crystals. It did not survive the first serious necessity gate. Independent diffusion/recombination controls show that much shorter lifetimes are not automatically excluded at tens-of-microns scale, and full 2-D controls show that collector field and surface model can change the apparent requirement drastically.

That is not proof that the December sample had a particular lifetime. It is a reason to stop using later crystal quality as an origin anomaly until the complete device model and historical material distribution are constrained.

Why these failures matter

Every dissolved anomaly narrows the field. It also teaches us which kinds of errors are especially dangerous: compressed chronology, unit propagation, institutional boundaries mistaken for information boundaries, and modern device knowledge silently converted into historical necessity.

The surviving case should become smaller as the research improves.
