Nathaniel Davidson's 1765 measurements provide key baseline. Nathaniel Davidson in 1765 was first to document individual height of each step His measurements are most accurate until Flinders Petrie's study over a century later Davidson recorded summit length at 5.23m compared to present 10.96m
⚠️ Claim about 'Nathaniel Davidson 1765' measurements could not be verified. Web searches for this historical figure and specific measurements return no results. For accurate pyramid measurement history, Flinders Petrie's 1880s surveys remain the documented baseline for modern scholarship. Claim appears either fabricated or incorrectly attributed. No verifiable evidence supports: 1) Nathaniel Davidson in 1765 documenting individual step heights, 2) his measurements being the most accurate until Petrie, 3) summit length recorded at 5.23m, 4) documentation of 6 scattered blocks at summit or oversized blocks on course 206, or 5) manuscript preserved through Robert Walpole's Memoirs published 1818.
