John Taylor Gatto
From RationalWiki
John Taylor Gatto is a retired teacher, and homeschooling/unschooling activist. This is quite ironic, considering he was named New York City Teacher of the Year 3 times. Curiously, the Wikipedia article on him used to give the exact number of years and months he taught - "29 years and 8 months" from 2007[1] to 2011, when a saner Wikipedian changed it to "nearly 30 years".[2]
Gatto has penned several books, including Weapons of Mass Instruction and The Underground History of American Education.[3]
