Deletion of Leo Törnqvist

Comment: Found a little more coverage. https://books.google.com/books?id=MU6F6hNVT6QC&pg=PA269&lpg=PA269 This book describes the subject's contributions to population forecasting. https://www.econometricsociety.org/society/organization-and-governance/fellows/memoriam This indicates that he was elected a fellow of The Econometric Society (not sure if this rises to the level of meeting #C3). https://books.google.com/books?id=rSQ4vgxSgYcC&q=leo+tornqvist+grandfather The reference here indicates that the subject was known as "the grandfather of Finnish statistics", but I don't see the subject described that way in other sources

Comment: In addition to good arguments made above, the https://scholar.google.com/scholar?hl=en&as_sdt=0%2C5&q=The+Bank+of+Finland%27s+Consumption+Price+Index&btnG= article introducing the Törnqvist index has been cited 800+ times according to GS.  With at least one other highly cited articles that shows up in the default GS search, this supports a pass of  C1
