  • Personal life

    Jonestown Tragedy

    During his childhood, several members of Valentine's family joined the People's Temple, a religious movement in Northern California. His Aunt Deborah Layton, Uncle Lawrence Layton, Grandmother Lisa Layton, and other family members all moved with the congregation to Jonestown Guyana. As described in his Aunt's book Seductive Poison, five-year-old Valentine played an unwitting but dramatic role in the return of his Aunt, Deborah Layton, to the United States, which enabled her testimony to members of congress about the conditions in Jonestown, [193] in-turn prompting the doomed visit of Congressman Leo Ryan to Guyana.

    Photography

    Valentine is an amateur photographer and his images have been published in a number of on-line venues. His images have also been used as cover art for various scientific journals and reports including the Proceedings of the National Academy of Sciences, [194] [195] Geophysical Research Letters, Environmental Science and Technology, [196] Applied and Environmental Microbiology, [197] EOS, [198] and by the National Academies. [199]
