Isaac Pitman and Alexander John Ellis jointly developed the English Phonotypic Alphabet (EPA), dated 1843 and completed 1845, as an English-language spelling-reform project: "The English Phonotypic Alphabet (EPA) is a phonetic alphabet developed by Sir Isaac Pitman and Alexander John Ellis, originally as an English language spelling reform." Later editions extended the EPA to German, Arabic, Sanskrit, and other languages.

The collaboration puts Pitman directly inside the vault's existing Lepsius → Ellis → Sweet → IPA notation lineage, where Ellis is already documented as the pivot who carried Palaeotype forward into Sweet's Romic and the 1888 IPA. This note adds the collaborator Ellis worked with on an earlier, separate reform project — and that collaborator is also, independently, the inventor of Gabelsberger shorthand's named point of mechanical contrast (see claim-gabelsberger-shorthand-never-omits-vowels-unlike-pitman). Pitman is therefore the single person who sits inside both the vault's Gabelsberger-shorthand cluster and its Lepsius-to-IPA lineage, a bridge the vault's own retrieval tooling had flagged as an unlinked candidate before this capture confirmed it (see observation-isaac-pitman-bridges-gabelsberger-shorthand-and-ipa-clusters).
