Mark went on to script shows at planetaria and museums across the country. He is also well published and highly regarded in the science fiction field. His story “What Dreams Are Made On” was reprinted in the 4th edition of Literature and Ourselves: a Thematic Introduction for Readers and Writers — making Mark a writer of academic significance. Mark is also listed in Brave New Words: The Oxford Dictionary of Science Fiction as having the earliest use of “morph” in a professionally published story “Being Human”.
But the things Mark was known best for can’t be quantified by the remarkable facts of his life, like his dry and mischievous sense of humor, his infectious grin, his fierce friendship, his braininess and insight, and his love and generosity. He’ll never truly be gone as long as we remember him.
