Thomas Harold Loy, 1942 — 2005
Dr. Tom Loy, molecular archaeologist, was born in Los Angeles, California
in February, 1942 and died at his home in Brisbane Australia in October
2005 of natural causes. At the time of his death, he was a Senior
Lecturer in the School of Social Science, University of Queensland, Brisbane,
Australia. His research interests included hominid tool use at Pliocene/Early
Pleistocene cave sites in South Africa, tools of the Italo/Austrian Ice Man
Mummy (Ötzi), and theory and logic in archaeology.
A memorial service for Tom was held November 7th at the University of Queensland.

Thomas Harold Loy was born in 1942 in Los Angeles, USA. His father, Harold
Amos Loy, was a fourth generation Methodist minister. His mother, Maxine,
was the daughter of Thomas Max Reitz, a Kansas farmer. All T. Max
Reitz's sons became Ph.Ds in agriculture. Maxine, an accomplished
singer and pianist, received a BA in music. When Tom was born, W.W.II
was underway. Our parents were strong advocates of what was called
in those days the Social Gospel. They were pacifists, and marched
against the war in the streets of Los Angeles. When Japanese Americans were
sent off to internment camps, our parents helped care for their property
until they could return. When the Japanese Americans were finally
released at the end of the war, Harold preached from his pulpit that they
should be welcomed back to the community as loyal Americans. Some
in the congregation stood up and walked out. During the 1950's, black
Americans were struggling for equality and freedom in the US. In response,
Maxine and Harold developed a program of Black (Negro) Spirituals, which
they performed in churches in Southern California, teaching racial tolerance
to white audiences.
When they moved to Glendale Arizona in the late 1940's Harold and Maxine
carried their social ministry to the native Navajo peoples in that area.
Tom became friends with the Navajo children. Tom strongly identified
with the Navajo, and from then on his life was devoted to understanding indigenous
people of the world, and their cultures.
Tom loved the out-of-doors. Our family was poor, so our vacations
were mostly camping trips to the Mojave Desert or backpacking in the Sierras.
Tom and Dad found a Pleistocene horse jawbone, dinosaur bones, trilobites,
and many kinds of semiprecious gems. Tom became a proficient outdoorsman
through the Boy Scouts, able to live in the wilderness on his own for weeks
on end by age 16.
Upon graduation from Chino High School in 1959, he attended Redlands University.
He was strongly influenced by the Beat poetry movement in San Francisco,
and and became a fine poet himself (see his poem
below). He once rode a Lambretta motor scooter 500 miles to San
Francisco to attend poetry readings at City Lights Bookstore and to see trumpeter
Miles Davis at the Hungry I. He graduated with a B.Sc. (Geology) from
Redlands University in 1964.
He served his country in the Army Reserve. Afterwards, he moved to
Alaska, taking a job as a cartographer for United States Geological Survey,
later working on an oil rig, and prospecting. He routinely went prospecting
for months at a time in the Arctic outback, looking mostly for nickel. He
told fascinating stories of his adventures with blizzards, bears, moose,
and near starvation when he missed a supply drop from a bush pilot. (He said
he killed an old goat to survive until the next drop.) He loved the
roughneck culture of Alaska, and enjoyed playing washtub bass with the Glacier
Valley Boys at the Double Muskie restaurant and bar. He eventually
completed an MA (Anthropology/Archaeology), from the University of British
Columbia. He performed Field work in the Frazier River Valley, Muncho Lake,
and in Yoho Park in the Canadian Rockies. Tom could read the earth like an
open book. His facility with living off the land gave him an uncanny ability
to identify archeological sites and find fossil remains. His focus
was always on the people who had used the artifacts he found.
Blood from a Stone
About this time, Tom made a discovery that was to propel him into the forefront
of science and establish his world class reputation. He was personally responsible
for the creation of an entire sub discipline of archaeological research
known as residue analysis.
In 1981, while working for the British Columbia Provincial Museum, he became
curious about the organic residues on the surface of the stone tools he'd
been excavating. The received analytical wisdom of the time was that this
was just dirt to be washed off before curating the artifacts. Tom asked
the elementary question: what was this material? Tom used the new
electron microscope at his museum to photograph the residue of an unwashed
obsidian arrow point at high magnification. A medical scientist colleague
of his confirmed that the residue included red blood cells preserved on
the face of the artifact. The discovery site of the arrowhead was thousands
of years old, which meant that the residue was that old as well.
This raised many questions: how could the proteins on the artifact survive
intact for a millennium? What kind of animal's blood was this? If its type
could be determined, a new window would be opened into the hunting habits
of ancient indigenous peoples worldwide. Was this preservation common, or
a fluke? In what circumstances and over what ages could such residues be
found? His answers to these questions led to the publication of his famous
paper (Science 1983). His work
struck a chord in the public imagination. Numerous newspaper articles talked
about the scientist who could extract blood from a stone. There is no doubt
that Tom was the world pioneer in this field. And there is no doubt that
being a pioneer is risky and dangerous in science. His theories were angrily
challenged by some, and his work came under suspicion even in the court of
public opinion. In the mid 1980's, the Museum administration proved
that it had no spine for the controversy by firing him from his position
on trumped-up charges.
But he shortly received an opportunity to continue his research in Australia
via an appointment to Australian National University, Canberra. He was able
to refine his research methods, teach, and finish his Ph.D. With the
help of his colleagues, the thesis of his Science article was eventually
vindicated, and he gained an international reputation for his work, with
publications in such journals as Antiquity (see References). Later, he accepted a position at UQ
in Brisbane where he lived and worked until his death.
As an indication of his high esteem, he was invited by the authorities
in Innsbruck, Austria to help investigate Ötzi the Iceman, arguably
the prehistoric archeological find of the last century. Tom studied Ötzi's
tools, clothes, and other artifact residues, and later helped establish
the Iceman’s cause of death. To be a member of such a select team of scientists
reflected well not only on Tom, but also on the scientific establishment
in Australia that provided him with a home for his research for over 20 years.
As he was nearing retirement, he was also beginning to wear out physically.
He suffered all his life from a hereditary blood deficiency. He complained
of headaches and feeling faint. He was not well. He consulted a doctor,
took medical leave that was due to him, and planned to go to Camooweal,
site of much of his recent research, to open an archeological field school
there. Because he chose to conduct research in such far-flung places in
the world, he was out of reach of family and friends for long stretches
of time. He always had a suitcase with clean clothes ready to fly
off on his next adventure, which you'd typically hear about only when he
got back. He never made it to Camooweal, but died in his house. He
is survived by his children, Curtis, Inge, Kim, Adam, Max, and Emma.
Tom had a deep appreciation for the ephemeral nature of his human existence,
as illustrated in his poem "Los Serranos," excerpted below. The setting
of the poem is the mist shrouded rolling hills of his home in Chino, California
where he and his father occasionally played golf together.
Los Serranos (excerpt)
Out of the mists of an early summer dawn
when the coolness of the air promises a hot afternoon
ghost gums float in the gray-green sea of grass
and the night smells are only just gone
two figures, father and son, walk some distance apart
up a long incline, guided by a small flag
The memory of the flight of our small white balls pull us over the hills
where once, banditos and their silver horses jingled through the same
mists of summer –
Stealing time, pulling us through the hole in the past opened by the morning:
Each strike of the ball is an unrecoverable unit of time,
time reduced to just that moment
the last shot forgotten, the next awaiting in the galactic unreachable
And they, the father and the son, leave behind only the worm tracks of
balls rolling in the dew
and footprints leading into the mist.
