Career
Though Reuss was later unmasked as a police spy, both Dave and Peukert were discredited by the dispute. Dave often offered French lessons in the Commonweal, and he collaborated in 1886 with Ernest Belfort Bax and William Morris on a pamphlet about the Paris Commune. He also published an obituary on Felix Pyat in the August 1889 Commonweal.
By 1900 he was living in Paris where he published a pamphlet on Bakunin and Marx.
In 1903 he was involved in the publication two translations from Lassalle. In Living My Life (1931), Emma Goldman records her favourable impression of Dave during a visit to Paris around 1900:
He was kindly and jovial.
Though sixty, he was as alert in mind and spirit as in his student days. Eking out a meagre existence as contributor to anarchist and other publications, he yet retained the buoyancy and humour of youth.
He was the freest and gayest among the many comrades I met in Paris, a companion after my own heart.
