Who wrote it is a different question from who was a Fellow Diagram

Curators are not automatically writers

Imported source-author metadata can identify a source writer, not the local curator.
References, image credits and people merely mentioned do not supply article authorship.
A supported credit is not the same as personal confirmation.

Identity is not an appointment

Merge name variants only on documented evidence or explicit confirmation.
A directory match cannot supply a missing article byline.
Guest authors and institute participants can write without being Fellows.

Keep missing evidence visible

No date match does not prove nonmembership.
Undated current roles are not extrapolated backward.
The author/year network counts publication credits, not appointments or productivity.
