Who's Uncle Robert? Google search attempts failed me

Context:

Polls suggest that approximately 95 per cent of the population
of the United States believe they will survive their own death. I can't
help wondering how many people who claim such belief really, in
their heart of hearts, hold it. If they were truly sincere, shouldn't
they all behave like the Abbot of Ampleforth? When Cardinal Basil
Hume told him that he was dying, the abbot was delighted for him:
'Congratulations! That's brilliant news. I wish I was coming with
155
you.' The abbot, it seems, really was a sincere believer. But it is
precisely because it is so rare and unexpected that his story catches
our attention, almost provokes our amusement - in a fashion
reminiscent of the cartoon of a young woman carrying a 'Make
love not war' banner, stark naked, and with a bystander exclaim-
ing, 'Now that's what I call sincerity!' Why don't all Christians and
Muslims say something like the abbot when they hear that a friend
is dying? When a devout woman is told by the doctor that she has
only months to live, why doesn't she beam with excited antici-
pation, as if she has just won a holiday in the Seychelles? 'I can't
wait!' Why don't faithful visitors at her bedside shower her with
messages for those that have gone before? 'Do give my love to
Uncle Robert when you see him . . .'
