Chern Medal

    

The obverse side (front) of the Chern Medal features the text "CHERN MEDAL" along the top rim and the portrait of Shiing-Shen Chern at age 73 in the center. Chern's Chinese signature is  to the left of the portrait, while his English signature sits to the right. The text "1911-2004" indicates the years of Chern's birth and passing, respectively. The reverse side (back) of the Medal displays the generalized Gauss-Bonnet theorem, elegantly and intrinsically proved by Chern in 1944, now frequently termed the Chern-Gauss- Bonnet theorem.  The name of the prize winner is engraved on the rim of the 2.5 inch medallion made of 18-karat green
gold plated with 24-karat gold. The medallions are designed and fabricated by Medallic Art, LP.
