Re: Our friend Bob Walters

Dear Giuseppe, dear all,

I am shocked to learn that Bob Walters is gone.
I knew him from the time I visited Max Kelly in Australia.
He was a very friendly person with a good sense of humor.
And a good mathematician too.
He was an adventurer, both in math and in life.
The last time I saw him was at the CT2010 meeting in Genova.
I am using his work with Carboni and Kasangian in my latest paper
with Gambino.

My deepest condoleance to his friends and family,
André

Dear Bill, dear all,

this is terribly sad news. I feared the worst when Bob did not show up at Cambridge for CT2014, but hoped that it was just a wrong feeling.

The strongest and happiest link I had with Bob was in the organization of two major conferences at Como and Genova: in both occasions the many, strangely difficult tasks which we had to confront always appeared easier than they were because of his willingness to make things work and of his amazing sense of humour.

My image of Bob is forever connected to cartesian bicategories (I, II, III,...). They constitute landmarks in the research in mathematics, and I am certain they will prove fundamental in the philosophy of the subject in the decades to come. It is the saddest of thoughts that I shall not discuss it with him any more.

At this terrible moment my heart is with Nicoletta and Sofia.
