'secret' is the definition.
(synonyms)

'one inventor recalled giving away organisation's' is the wordplay.
I cannot really understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
'organisation' could be 'side' (side is a kind of organization) and 'side' is located in the answer.
A single letter 'n' remains which might be clued in a way I don't see.
This explanation may well be incorrect...

'first' acts as a link.
