Frei Otto e Fiedler tornaram-se amigos após 3 anos de cartas enviadas do Brasil, onde Nelson Fiedler buscava aprender com seu aspiracional mentor. Otto encontra em Fiedler um engenheiro jovem com mente firme a um grande futuro. Adiante destes dias como pode ser visto nas fotos formou se uma ótima cooperação.

Intermediado por Nelson Fiedler, o encontro entre Frei Otto e Oscar Niemayer onde puderam falar sobre a leveza das tensoestruturas e das cascas em concretro armado. muitos aspectos da vida foram tratados como música, urbanismo e amor.

Nelson Fiedler ficou impressionado com a quantidade de conhecimento trocada neste dia e com a similaridade nas linhas de design dos dois famosos e geniais arquitetos.
