Guido Altarelli (July 12, 1941 – September 30, 2015)

Guido Altarelli passed away on September 30th after a lengthy fight against illness.

Many memories rush to mind, as tears to our eyes.

His ironic humour, his warmth, his kindness, his integrity,

his magnificent smile. A pillar of our group is gone.

His great contributions to physics will be a lasting

tribute to his memory. Guido will live on in our hearts.

Today is a day of great sorrow for the Theory Division.
