The K-T Letters/A Letter by Luis Alvarez



Dear PaleoNet Colleagues:

	Many people who contact me on the K-T express surprise to have
learned that my Deccan Traps-greenhouse K-T extinction theory was being
developed at the same time as the Alvarez asteroid theory. This shows how
powerful cliques, who control the news media, and who go after their
opponents to wreck their credibility and careers, can promote their theory
to the status of "truth," while demoting their opponent's to near oblivion.
I'm not the only one who was attacked by impactors.

	After the impactors nearly wrecked my career in the mid 1980s,
Chuck Officer tried to take over leadership of the volcano side of the K-T
debate. The impactors also hit him with politics. Today, it's Gerta Keller.
At the 1994 Snowbird III conference Gerta--who had to leave the meeting
early because of a severe ice storm in the eastern U.S.--became the focus
of a small band of vocal impactors: "We can throw out Keller's entire K-T
data base," "Keller is a coward who got out of Dodge," etc.

	For an example of how Luis Alvarez operated to politically damage
his opponents, I share the following.

	In March 1984, David Raup and Luis Alvarez cohosted a workshop on
mass extinctions, etc., at Berkeley. It consisted of 30 invited
participants. Of course, I was not invited. After my two-day 1981 K-TEC II
debate with the Alvarez team where I argued that the K-T iridium--the sole
"evidence" of the asteroid theory--was likely released by the Deccan Traps
volcanism, Alvarez wanted nothing more to do with me. But that did not mean
that Alvarez was through trying to damage my credibility, or to isolate me
out of the mainstream of K-T science.

	My non-invitation to the Berkeley workshop gave Alvarez yet another
means by which to attack me. It was to the effect that "Nobody invites
Dewey McLean to conferences anymore."

	I have in my possession Luis Alvarez's 4 January 1984 letter to a
prominent physicist who had published an article in a popular science
magazine critical of the Alvarez asteroid. Alvarez wrote the physicist a
letter attempting to intimidate him by using me as an example of what can
happen to his opponents.

	Following are quotes from the Alvarez letter which is on Lawrence
Berkeley letterhead, and signed by Luis Alvarez:

	"As a horrible example of what can happen to a scientist when he
clearly--in sight of all his peers--ignores important evidence, I'll remind
you of Dewey McLean, a paleontologist from V.P.I. Dewey used to be invited
to all the conferences and debates about the K-T extinction. But he no
longer is, because he refuses to face up to the fact that the Ir
enhancement is of great importance in understanding what happened 65
million years ago... So Dewey is now a forgotten person in the field, or
when he is remembered, it is only for a few good laughs, at the cocktail
party at the end of the Deweyless meeting."

	"****, I'm sorry to say that I see you going down the Dewey McLean
lane."

	"So, ****, please stop grasping at such tenuous straws--unless you
really _want_ to emulate Dewey."

	Alvarez repeated this criticism in a 19 January 1988 _New York
Times_ article. His statement: "If the president of the college had asked
me what I thought about Dewey McLean, I'd say he's a weak sister. I thought
he'd been knocked out of the ball game and had just disappeared, because
nobody invites him to conferences anymore."

	This sort of attack upon me by Alvarez and his paleobiologist
cohorts was hand carried into our V.P.I. geology department.

 	In January 1982, one of my V.P.I. colleagues attended a meeting on
the Stanford campus together with Luis Alvarez. My colleague's 4 December
1988 letter to me--written after some bitter confrontations--states,
"...based on my own conversation with Luis Alvarez in January, 1982, was
that he was not 'fighting fair'...." And "...the unfair criticisms of your
work by the 'Alvarez camp'...." And "...their unfairness was widely
known...."

Cordially,
Dewey McLean
