A thorough biography was published in 1976[3] although it omits his expressed enjoyment of editing anthologies of poetry. While in 1940, Sladen refers to himself as "an editor of anthologies" as he did in the foreword for his friend Ella Grainger (nee Strom).[4]When Ella Grainger, by then married to Percy Grainger, returned to England for a visit, Sladen was "rejoiced to find that she had brought with her a collection of poems ready for publication".
