In their writing partnership, Van Dooren wrote, Jos Deckkers criticized and Jef Beeckmans corrected grammar and language.

Their forty-year friendship was based on their mutual interests in Esperanto, philosophy, and literature.{{Citation needed|date=January 2025}}

After the deaths of Beeckmans (1975) and Deckkers (1979), their heirs gave van Dooren the right to finish works that the group had already been begun.{{Citation needed|date=January 2025}}
