Marc Segar was a British autist who died in a car accident in 1997 at the age of 23 years old.
Despite his short life, Marc’s legacy includes two books: The Battles of the Autistic Thinker, and A Survival Guide for people with Asperger Syndrome. The Survival Guide was one of the original ‘first-person’ accounts of Asperger’s Syndrome, and has been widely praised for it’s applicability to real life scenarios. The Guide has been translated into French and German, and remains relevant today. Both books can be freely downloaded from sources including Autism and Computing, and a pdf version that prints well was made available by Alistair Edwards of the University of York.
Marc’s legacy, however, goes further than the original books. Since 2005, the Survival Guide has continued as a WikiBook, which you can read and contribute to online. There is continuing interest in it, borne out by an average of 400 views each month, but recently editing has diminished, so it has not changed for nearly a year. Do please take a look at the Guide, and see if there is a contribution you can make to it; for example, the existing Guide does not say anything about getting married or raising kids. Even if you can’t find something to add, you will still find it a very worthwhile read, and a WikiBook, pdf and printable versions are offered. 
If this topic interests you, do please take a look at my previous review of four other Free Autism Spectrum e-books, and I just want to thank Martin Poulter for initially drawing my attention to the Guide.
