Dr. Andrew Woolf,
Bureau of Meteorology
I Keep six honest serving-men:

The Elephant’s Child (Just So Stories, 1902)

Ranganathan’s PMEST
(according to commentators)
Hermagoras of Temnos (1st century BC).
‘Seven circumstances’ as loci of any hypothetical question:
quis
quid
quando ubi
who? what? when?
cur
quem ad modum quibus adminiculis
where? why? in what way?
by what means?
‘Five Ws’ as facets for environmental
information?
