"Causal fermion systems were introduced by Felix Finster and collaborators." if this is true, then Holland maybe introduced the idea during 1998

"The causal interpretation of quantum mechanics is extended to include Fermi fields." in https://www.sciencedirect.com/science/article/abs/pii/037596018891033X P.R.Holland 1998

The first dated papers showing the exact "Causal fermion systems" Felix Finster (in google scholar) seem to date to 2012:

Holland's paper not related to causal fermion systems

It is correct that causal fermion systems were introduced in 2012. Although its title contains the words "causal" and "Fermi", the paper by Holland is indeed not related to causal fermion systems. It also does not contain any preliminary ideas or methods which led to causal fermion systems.

Causal fermion systems are based on the "principle of the fermionic projector" formulated in hep-th/0001048. The considerations which led from the "principle of the fermionic projector" to causal fermion systems are outlined in the "Preface to the second online edition" in the latest version of hep-th/0001048. The first reference to the "principle of the fermionic projector" can be found in the unpublished preprint gr-qc/9606040.
