Inventor to shout with information technology beginning to happen? (9)

I believe the answer is:

hollerith

'inventor' is the definition.
(US inventor Herman Hollerith)

'shout with information technology beginning to happen?' is the wordplay.
'shout' becomes 'holler' (to holler is to shout or yell).
'with' means one lot of letters go next to another.
'information technology' becomes 'IT' (common abbreviation).
'beginning to' says to take the initial letters.
The initial letter of 'happen' is 'h'.
'holler'+'it'+'h'='HOLLERITH'

'to' is the link.
