Freethought movement

Throughout the 1980s, Seckel was active in the Freethought movement and generated a number of articles and pamphlets. He also edited two books on the English rationalist philosopher Bertrand Russell. In 1983, Seckel and John Edwards co-created the Darwin fish design, which was first sold as a bumper sticker and on T-shirts in 1983–84 by a southern California group called Atheists United.^[5] Chris Gilman, a Hollywood prop maker, began to manufacture plastic car ornaments with the Darwin fish in 1990, and licensed the design to Evolution Design of Austin, Texas.^[6] When the emblem evolved into a million-dollar business, Evolution Design threatened to sue distributors of look-alike and derivative products. Seckel in turn sued Evolution Design for copyright infringement. Although Seckel produced examples of the design that predated Gilman's 1990 copyright date, the suit was settled when it was determined that Seckel and Edwards had allowed the design to fall into public domain.^[5]

In 1984, Seckel started the Southern California Skeptics (SCS) and became a spokesperson for science and its relationship to the paranormal.^[7] SCS co-sponsored and produced a monthly series of lectures, primarily held at the California Institute of Technology, with other meetings occasionally held on the campus of Cal State Fullerton, that explained alleged paranormal phenomena such as extra-sensory perception and firewalking.^[8][9][10] Seckel was the founder and executive diretor of SCS.^[2] An article published in New Scientist in 1985 states that the Southern California Skeptics were "the fastest growing chapter of the Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP)".^[11] Author George P. Hansen, in an article published in 1992, stated that incidents involving Seckel had embarrassed CSICOP because "he did not hold the academic credentials he claimed."^[12]

The Southern California Skeptics dissolved after the late 1980s. In 1991, Michael Shermer and Pat Linse co-founded a new Los Angeles-area skeptical group called The Skeptics Society^[13][14] after the Southern California Skeptics had disbanded.^[15][16][17]

Visual illusions

Seckel was "a leading collector and popularizer" of optical illusions.^[4]

In 1994, he created an interactive website on illusions.^[18][19] He also developed visual illusion installations for museums.^[20]

Seckel's books about optical illusions include several picture books for children such as Ambiguous Illusions (2005), Action Optical Illusions (2005) and Stereo Optical Illusions (2006).

His book, Masters of Deception: Escher, Dali, and the Artists of Optical Illusion (2004), collects the work of many visual illusion artists, including among others Giuseppe Arcimboldo (1527–1593), Salvador Dalí (1904–1989), M. C. Escher (1898–1972), and Rex Whistler (1905–1944). His book The Art of Optical Illusions placed first on the American Library Association's "Top 10 Quick Picks for Reluctant Young Adult Readers" list for 2001.^[21]

He gave many lectures about such illusions, including an early TED talk (2004) and a talk at the World Economic Forum, Davos in 2011.^[4]

Rare book investment and sales

During the late 1990s, Seckel collected the papers of a number of early molecular biologists (including Rosalind Franklin, Aaron Klug, Max Perutz, Rollin Hotchkiss, and Sven Furberg) for rare-book dealer Jeremy Norman.^[22][23] At the time they were collected, the market value of the archive was unknown as many institutions did not have an interest in keeping the archives of scientists.^[24] After the Wellcome Trust purchased the papers of Francis Crick in 2001 for $2.4 million, Norman pursued individual sale of the items in his collection through Christie's.^[24] A lawsuit prevented the individual sale of the items by Norman.^[22] Seckel and Norman had a falling out.^[25] According to Seckel, the sale was canceled due to his extensive documentation that was brought to the attention of Christie's.^[26] Although former colleagues and associates of James Watson and Crick attempted to raise the asking price of $3.2 million in an effort to have the collection donated to the Cold Spring Harbor Laboratory, the collection was eventually acquired by molecular biologist J. Craig Venter, with the stated aim of keeping the critical resource available to scholars by housing it at the J. Craig Venter Institute.^[24]

Lawsuits and disputes

Seckel was sued on several occasions after disputes over rare-book investment and sales.^[4][27]

In a San Diego Reader article from 1994, Tom McIver (author of Anti-Evolution: An Annotated Bibliography) accused Seckel of failing to disclose financial information as leader of the Southern California Skeptics and misrepresenting his academic credentials.^[28] Seckel later sued McIver for libel over edits to his Wikipedia page. The suit was settled in 2007 under undisclosed terms.^[4]

A 2015 profile of Seckel in Tablet Magazine by Mark Oppenheimer detailed several first-person accounts from individuals who reported that Seckel still owed them money including the widow of one of his mentors, his lawyer, a graduate student, and those who had engaged in rare book deals. The article stated that there were at least 25 cases involving Seckel from 1992 to 2015 in the Los Angeles Superior Court database.^[4] Oppenheimer reported that Seckel cultivated a false image, both with personal contacts and within the media, of himself as a graduate from Cornell with degrees in physics and math, as an affiliate of and candidate for doctoral degrees at Caltech, and as a scientist conducting research in conjunction with colleagues at Harvard University. Some of these inaccuracies were published in media coverage of Seckel, including in the Los Angeles Times in 1985^[9] and 1987.^[4][10]

Seckel was later accused of absconding with over $500,000.^[29]

Collaboration with Jeffrey Epstein

In 2009, Seckel was involved in organizing a science conference with financier and convicted sex offender Jeffrey Epstein. The Mindshift conference took place in early 2011 on Epstein's private island Little Saint James.^[30][31] In attendance were scientists Murray Gell-Mann, Leonard Mlodinow, Gerald Sussman,^[27] and Frances Arnold,^[31] in addition to the actor and cryptocurrency proponent Brock Pierce.^[30][31]

An interview between Jeffrey Epstein and Al Seckel discussing perception appeared on Epstein's science website on October 17, 2010.^[32]
