I’m enjoying a lot at this time reading the book “Eduardo Torroja, Engineer” (Ed. Pronaos, 1999, dual Spanish-English) by José Antonio Fernández Ordóñez and José Ramón Navarro Vera. It’s a very complete book about one of the greatest civil engineers of the history: the technical-artistical historic context, the relationships with another great engineers, and exhaustive review of his works:Zarzuela Racecourse, Algeciras Market, Sancti Spirit Chapel… and, of course, the milestone Frontón Recoletos.
I found via En.Wikipedia an… errr… brochure about this book
