Felix Candela
Probably unbeknownst to most people from Ottumwa when the new Walsh High School opened in 1962 students stepped into an unusual building using a design by one of the most famous architects of the 20th century, Felix Candela.
Born in Madrid , Spain  in 1910, Candela was a national sports champion in Spain  and a noted award-winning architect who was pursuing graduate studies in Germany 
He left school to return to Spain  and fight for the Republic against Franco and when Franco won he slipped into a refugee camp in France  to avoid becoming a prisoner of the Franco regime.  In 1939 he was selected for relocation to Mexico  and moved to his new home.
In Mexico Candela pioneered the use of thin shelled concrete in building construction and among the nearly 1,000 buildings he designed were the revolutionary 1968 Olympic Stadium in Mexico City  and the Basilica of Our Lady of Guadalupe in Mexico City 
The Guadalupe Basilica is the most popular Catholic pilgrimage site in the world drawing over 20 million visitors annually to see the tilma of Juan Diego with the image of Our Lady that was made December 12, 1531.
As a point of reference, at that time America 
Candela developed a thin shelled concrete material for use in buildings called the "hyperbolic paraboloid" and his structures are located in Mexico , the United States , Spain , Venezuela , Columbia , Peru , Guatemala , Puerto Rico , Ecuador , Great Britain  and Norway 
My father, Wayne E. Putnam arranged with Felix to use his designs for the new Walsh  High School 
Local architects for both of the projects were Ken Steffen and Steve Stoltz.
Felix moved with his family to the United States  in 1971 and taught at Harvard University and the University  of Illinois North Carolina
