Karl Richard Lepsius, later famous for a universal phonetic alphabet, was also a founding practitioner of the epigraphic 'squeeze' — a moist-paper impression that copies an inscription 1:1 without touching it

A squeeze (or estampage) is a physical, reverse-image copy of an inscribed surface: "a reverse copy of an inscription, made by applying moist filter paper and pushing into the indentations by percussive use of a stiff brush." Beaten into the stone while wet and lifted once dry, it captures the incised text at true 1:1 scale without contact damage to the original. The technique survived the invention of photography precisely because it preserves absolute scale, which a photograph distorts in isolation — squeezes remain in working use in epigraphy today.

Karl Richard Lepsius (1810–1884) — the Prussian scholar later known for the Standard Alphabet — is credited among the founding practitioners of large-scale squeeze and cast production, from his 1842–45 Prussian expedition to Egypt, where the transcription demands of hieroglyphic and African-language material drove the method. The much-cited corpus size (~6,000 squeezes) is search-synthesized and unverified against a primary source; it is recorded here only as flagged, not asserted.

The note's cross-domain interest is the single-person overlap: the same figure helped establish a physical text-reproduction technology and a notation system, both of which turn on the cost of faithfully reproducing marks. This places Lepsius inside the vault's physical-reproduction-constraint thread alongside claim-early-modern-printers-corrected-print-with-cancel-slips, claim-bomberg-1520s-venice-talmud-set-standard-page-layout, and claim-djvu-created-to-freely-distribute-scanned-documents — with the twist that the squeeze is a pre-photographic answer to the same fidelity problem those later cases confront in print and scan.
