Dear Friends,


It was a sad day for me when I heard that Alberto, the Alberto we all respected, enjoyed and looked forward to spending time with, is not with us anymore. Alberto enjoyed people and was fun to be with. However, for me it was his deep respect and care for the many people he encountered that impressed me most.


My academic career began with a joint paper with Alberto and I was still discussing joint research with him not long ago. Of course, with Alberto life went well beyond research. I have so many fond memories from our many encounters and discussions in so many different places. So, I was grateful that one time I had the chance to give back a bit and this is the story.


In one of the Israel Stringology workshops that I co-organized with Ami, Gadi and Ely I found myself in charge of the day trip. Ami and Gadi were both checking out the possibility of rector positions in their respective universities and could not join the trip. Ely, likewise, was busy. So, I decided that the desert/dead sea would be a great trip. Alberto joined but he was already not feeling well. So, when we all descended from the bus to hike in the desert (which included some climbing) he decided not to join. I felt bad. However, the next two stops were exactly to his taste. He was very taken with the historic guide on top of Masada and he fully used the time floating in the dead-sea water pool in the hotel on the dead-sea beach. Finally, at dinner he was glowing again and graciously thanking me for "this most wonderful day".  He explained that "unlike sailing, the virtue of the dead-sea water is that you do not need to make an effort to enjoy."


In fact, I regret not taking him up on his offer to sail around the whole Italy in his yacht. I would surely NOT have enjoyed the sailing. However, I missed out on two weeks with Alberto  -  a big mistake.


I add a couple of Alberto stories that I would like to share.


The Levenshtein-distance

In 2003 Prof. Rudi Ahlswede from Bielefeld University was funded by ZIF (in Bielefeld)  to organize a yearlong string of workshops on "Information Transfer and Combinatorics". Vladimir Levenshtein, who defined the Levenshtein-distance, was there for several months with a group of fellow researchers from Moscow. Alberto was also a long-term guest and was asked to form his own part-time group. I was a young, new faculty member in Bar-Ilan University and was more than happy to join when Alberto graciously invited me. My three visits lasted for about a month in total. For those of you who know Bielefeld – that is a lot of time.

Fortunately, Alberto took his "group responsibility" very seriously and after research during the day he entertained us in the evenings with stories, discussions and wine. Towards the end of one of these visits pictures were being taken of the group. Suddenly Alberto's eyes lit up and he asked Vladimir to stand next to him and for me to stand on his other side. With a big smile to the camera he said "I am the Levenshtein-distance".

 

The Ride to Georgia-Tech Lorraine

I was sitting one afternoon in the mess room of Dagstuhl with Alberto when he turned to me and asked "Did you know that Georgia Tech has a campus not far from here?" Obviously, I did not. "You know it is near Metz" he told me. "Have you ever been to Metz?" he asked. I had not. "Moshe, Metz is a wonderful city. It has an amazing church and a wonderful old city. You must come and see it." This is how I was (unknowingly) convinced to join him on the 200 KM trip (100 in each direction) to check out a potential sabbatical for Alberto in Georgia-Tech Lorraine.

I do not regret making that trip.

 

With fond memories,
Moshe

Dear all,

There are two memories that immediately came to my mind when I’ve
heard Alberto left us: the first and last time I saw him. I’d like to
share them, together with a story. They are just a little addition to
all that has already been said about Alberto, but it is a little
addition that counts a lot to me.

At the beginning of 2002 Alberto and Titti played what I would
definitely call a crucial role in my life. After my master degree in
2001 I started to work in the industry, at Telecom Italia Labs. An
interesting job, but feeling I was missing something I did apply for
the PhD program in Padova.  When I was admitted I seek for a PhD
advisor, but for one reason or the other my search was not as
expected. So, I went to Titti, who was the PhD program coordinator, to
tell her I would have stayed in the industry. She suggested talking to
Alberto, who I hadn’t consulted yet, before making a final decision,
and led me to his office. That afternoon I had a long chat with
Alberto. I found myself in front of someone not only highly
knowledgeable, but so passionate and enthusiast about research to be
contagious. He helped me ponder pros and cons of my alternatives, with
deep argumentations, and finally he gave me a paper, “Of maps bigger
than the empire”, saying if I had liked it, I would have known what to
do. The following day I returned to Turin, where I was working, and
told my boss I made up my mind. My PhD with Alberto had just begun.

As a by-side note, when we left Alberto’s office it was dark outside.
Considering the area nearby the university is not exactly the safer in
Padova, Alberto, being the gentleman he was, waited with me at the bus
stop, although he did not need to take the bus.

Two years ago I met Alberto at his hotel in Lipari, to discuss with
him some problems that would have lead, few months later, to my joint
paper with both Alberto and Titti! Then we were joined by my husband,
with my son, and by Titti, and we had a nice drink together on the
terrace. I remember Alberto showing his boat to my son, explaining to
him (who was not even two years old) that one was indeed a very good
boat, while those on the horizon were all “ugly” boats (or whatever
the translation of “schifezze” is!). That was the last time I saw him
in person. It was a really nice afternoon, and I will treasure it
forever.

Alberto liked to play jokes on me about few things. His favourite was
definitely cooking, although he never ate anything cooked by me (while
I ate something cooked by him, but this is another story). Here is how
it all began.


The tomato sauce.

Towards the end of my PhD I visited Alberto in West Lafayette and he
was so kind to help me settling. One day he drove me to buy some food
and then we went separately to search for what we needed. It was my
first time in the States and I was looking, without much success, for
familiar brands. When I had to choose some tomato sauce I was really
lost. I usually buy “passata di pomodoro” without any addition, which
is the basis for the tomato sauce. But I could not find it. The choice
was between ready-to-use tomato sauces, or to buy some tomatoes and
make the sauce myself. Now, I have to admit I am a bit lazy when it
comes to cooking, so I picked what looked to me as the simplest
ready-to-use sauce (i.e. tomato and basil). In that precise moment I
felt another presence. Alberto was in front of me, with a look of
great disapproval: “Not even I would ever buy something like that!” he
told me. Quickly I put the sauce back to the shelf, and ask him what
he usually bought (note that Titti was not there that semester for a
more reliable culinary advise). Alberto browsed the shelves and moved
further in the aisle till he found what he was looking for: “Ah, there
you are!”, and put a couple of cans in my shopping cart. Then he left
with a smile of satisfaction, maybe because he saved me from a deadly
sin for an Italian or, most likely, because he had found something to
playfully tease me on for the years to come. In any case, I was
curious to see what he put in my cart. I took one of the cans and it
was... Tomato Soup! Feeling a little less ashamed for my original
choice, a smile appeared on my face too, while following him to the
cash counter.

Since then I’ve heard several times, especially at dinner parties,
Alberto telling the story of my dreadful choice of tomato sauce, so to
explain to other guests why I was strictly forbidden to go any close
to the kitchen. I have to say he was so funny in telling the story
that it was only recently that I revealed to him that, if he was
really using what he put in my cart, he must have had “spaghetti with
tomato soup”!
