Margaret Ann Griffiths (1947-2009) was born and raised in London and lived for some time in Bracknell then later moved to Poole. Rather than seek publication through traditional channels, she was content to share her work with fellow poets on various Internet forums. On the rare occasions she submitted work for publication, it was typically to online venues. Also known by the Internet pseudonyms 'Grasshopper' and 'Maz', she began posting her poetry online in 2001. During the mid-2000s she worked from home, running a small Internet-based business, and edited the Poetry Worm, a monthly periodical distributed by email.
In 2008, her "Opening a Jar of Dead Sea Mud" won Eratosphere's annual Sonnet Bake-off, and was praised by Richard Wilbur. Later that year she was a Guest Poet on the Academy of American Poets website, where she was hailed as "one of the up-and-coming poets of our time".
She suffered for years from a stomach ailment which eventually proved fatal in July 2009. Almost immediately after her death was announced on Eratosphere, poets from all over the English-speaking world, from London, Derby, Scotland, Wales, Queensland, New South Wales, Massachusetts, New York, Minnesota, Missouri, Maryland, California and Texas collected her work for this publication.
