Alberto Calderón was a shy, courteous and modest man who, once comfortable, would open up and entertain his companions with ease.... I will not forget the kind, considerate and elegant gentleman, cigarette in hand, often seen walking quietly down the corridors of Eckhard Hall, in the University of Chicago.
Alberto Calderón ay isang mahiyain, magalang at katamtaman ang tao na, kapag kumportable na, ay bukas at isaalang-alang ang kanyang kasama na may kadalian.... Ako ay hindi malimutan ang mga uri, maunawain at matikas gentleman, sigarilyo sa kamay, madalas na makikita naglalakad tahimik na down ang corridors ng Eckhard Hall, sa University of Chicago.
