Charles Decker in his book 'Winning with the P&G99' tells us that P&G
employs 7,000 scientists working in seventeen research centers
throughout the world; of these, 1,250 have PhDs – more that the
combined science departments of Harvard, MIT, Stanford, Tokyo
University and London’s Imperial College. Can anyone give me
comparable information for Unilever?

There is no need to respond to this comment. I just wish
to inform you of the research underway.
Google searches provide an approximate number of scientists at
Unilever but no information on the number of PhDs. I have spoken to,
and emailed in confirmation, the Unilever Press Office and I await
their reply. One working day has passed since my request. I shall give
you the answer as soon as I receive it. I shall also keep you
regularily updated so you know that I have not forgotten you.

enquiry with them today.
