Acknowledgements

The editors and curators of the Atlantida website are indebted to the family members of João de Barros, in particular Eng. António de Barros, for their encouragement and collaboration, crucial elements of this online publication. We owe them our deepest gratitude.

We would also like to thank the availability and cooperation of Professors Vania Chaves, Zília Osório de Castro, Cláudia Poncioni, and Vírginia Camilotti for providing permission to record and edit the conferences presented as part of the Atlantida centennial commemorations.

Our gratitude also extends to Dr. Luís Sá, who always responded to our requests with the greatest diligence and care – as, indeed all other BNP technicians and senior staff – and suggested a number of relevant documents for publication.
