This file of correspondence contains letters to and from Kenneth MacMillan during his time as Ballet Director of the Deutsche Oper Berlin but is not primarily related to his work there.

It includes letters from Celia Franca at National Ballet of Canada, Gerd Larsen, Lucia Chase, Peter Darrell at Western Ballet Theatre, Erik Bruhn and Goran Gentele at Swedish Royal Ballet, Herman Hardenberg about Lynn Seymour, Mimi Paul, John Percival, Glen Tetley, Bronislava Nijinsky, Peter Wright, American Ballet Theatre, Jacobs Pillow, PACT Ballet, Capab Ballet and Ballet Nacional de Cuba

The Deutsche Oper Berlin performed Kenneth MacMillan's one-act ballet Las Hermanas in 1968 using the original designs by Nicholas Georgiadis. The letters in this file, two to Kenneth MacMillan and one to Gert [Reinholm] give details of Nicholas Georgiadis's fees and instructions for the set, props and costumes. The majority of the letter to Gert [Reinholm] appears to be written by someone else with just the closing sentence and signature by Nicholas Georgiadis. Georgiadis concludes one of the letters to MacMillan, 'And by the way try and be less rude on the phone'.

One typed letter from Alun Jones, Artistic Director of Louisville Ballet, asking if the Company can perform Las Hermanas; Galina Samsova requested to dance this with them with Desmond Kelly, 23 Oct 1980

Lucia Chase, dancer, co-founder and co-director of American Ballet Theatre, first met Kenneth MacMillan at the Royal Opera House, London in 1956. She immediately commissioned a new work from him for ABT which premiered the following year. She also took several of his works into the Company's repertoire and wrote often requesting a new work for her Company. The material in this file covers the first performance of Concerto, mentions of Las Hermanas, which Lucia Chase danced in, Danses concertantes, Romeo and Juliet and the creation of Pavane pas de deux for Gelsey [Kirkland] and Ivan [Nagy], and two covering letters enclosing payments for performances of Pavane pas de deux, Danses concertantes and Concerto during the Spring Season, 1978. There is an interdepartmental communication from Kenneth MacMillan to John Tooley about letting ABT perform Pavanne (sic), 14 Nov 1977

This file includes correspondence between Kenneth and Deborah MacMillan and Anne Woolliams, Peggy van Praagh and Robert Helpmann, impresarios Lilian and Victor Hochauser and Sol Hurok and the MacMillans' agent, concerning requests by The Australian Ballet to perform some of Kenneth MacMillan's ballets.
