Patrick "Chief" Parker |
“There’s a tanker
coming in!,” he shouted. I looked up from my table of data that I’d been
explaining to one of my major professors, Pat Parker, and glanced out the huge
picture window in his office onto the ship channel that funneled big oil
tankers into port from the Gulf of Mexico.
My other major
professor, Chase Van Baalen, sighed audibly and said, “Come on Parker, focus.”
Reluctantly, Parker resumed his on-again/off-again interest in my data on
isotopes and enzymes that formed the backbone of my PhD dissertation.
I’d come to grad
school in the small town of Port Aransas, Texas, expressly to work with Patrick
L. Parker. To a youngster from Penn State, I’d read all of his papers and
imagined him as a distinguished professor. In early January 1974, I flew down to
Texas from my family home in New Jersey. My one suitcase was filled with woolen
winter clothes, leather boots, and only a few summer things. I brought my
pillow and a typewriter. Professor Pat
Parker picked me up at the airport in his old VW bug, rusted out on the sides.
He was a modest looking man with a small mustache, a bit of a limp, and shaggy
brown hair. Even as the Director of the Institute, he wore old khakis and an
un-ironed short sleeve shirt with no tie. I had formed a different picture of
how he looked based on his Science papers that I had read at Penn State.
We drove to Port Aransas on Mustang
Island, where the University of Texas Marine Science Institute was located,
with the final portion of the journey via ferry. When we arrived on the island,
Parker drove his VW right out onto the beach, which surprised me. It was a
foggy day in January and it felt like we were on the edge of the continent,
which we were.

Pat served as the Director of the Marine
Science Institute, which seemed perpetually plagued by heavy Texas academic
politics. Fortunately for me, my other two professors Chase Van Baalen and Bob
Tabita had their feet on the ground and taught me everything I needed to know.
Parker saw the Big Picture. Parker and Van Baalen often sniped at each other,
but it was all in the sense of familiarity and camaraderie.
Parker’s lab was my first venture into the
field of stable isotopes. There was one aging Nuclide 6-inch isotope ratio mass
spectrometer with a glass vacuum line and mercury columns that served as the
inlet system. He had a gas chromatograph that sometimes worked, a lot of lipid
extraction glassware, and some ovens and balances.
Parker and Van Baalen, my major professors |
I learned Marine Chemistry from Parker.
Years later, former student John Hedges and I compared our memories of what
we’d learned about marine chemistry from him. We couldn’t recall much about the
ocean, but learned a heck of a lot about the Green River shale, a sedimentary
rock strata loaded with organic carbon. The Green River shale wasn’t
even formed in the ocean, but instead a freshwater lake system. Hedges and I
laughed over how we’d managed to succeed in marine chemistry regardless.
Students called Parker “Chief” or “the
Chief” depending on how you felt about him that day. I often wished he was more
involved in my work, but eventually learned that that wasn’t his strength.
He was actually a people person. Parker attracted students who shaped
the stable isotope and organic geochemistry field to a much greater extent than
most people realize. Although he was one of the early scientists at the Marine
Science Institute, he also had a 2-year postdoc at Carnegie’s Geophysical
Laboratory, then became a temporary staff member there for another couple of
years. It was at that time that he wrote his paper on “The biogeochemistry of the stable isotopes of
carbon in a marine bay” (Parker, 1964).
I believe this is
one of the earliest works on compound specific isotope measurements in fatty
acids, published just after Phil Abelson and Tom Hoering published their
landmark study on amino acids and isotopes (1961). Carbon isotope measurements
in lipid molecules weren’t investigated further until almost 25 years later
when Kate Freeman, Martin Schoell, Bob Dias, and John Hayes started the modern
technique that has exploded worldwide.
I’ll bet few people
these days recognize Parker’s contributions. Not only did he launch me into the
field of isotope biogeochemistry, but trained John I. Hedges, a marine organic
geochemist, Steve Macko, and Brian Fry—all of whom have been or are
tremendously productive people in biogeochemistry.
I kept in touch with
Pat until he passed away in 2011. He served as a mentor to me, making trips to DC
almost every year. That’s well over 30+ years of mentoring! One of his classic
lines in regard to the life of a scientist: “You’ll never be rich, but you’ll
be comfortable.” His insight into mentoring grad students: “You can teach ‘em
to read and write, but they have to think on their own.” In 1995 when Tom
Hoering was dying of brain cancer, Parker wrote to me knowing I was worried
about Tom. He said, “Don’t forget to relax once in awhile.”
The local newspaper, The South Jetty, had this to
say about Pat after he passed away:
“Parker served on the Port Aransas Independent
School District Board of Trustees throughout most of the period between 1965
and 1977. One year, when he didn’t file for office, he still won a seat on the
school board as a write-in candidate, according to his family.

Parker also was co-owner of Coastal Science Labs, a
small Austin-based business. The company’s Web site described the business like
this: ‘We are specialists in the analysis of stable isotope ratios of the light
elements carbon, nitrogen, hydrogen, oxygen and sulfur. Applications for this
type of analysis range from food adulteration detection to the exploration for
fossil fuels.’
After he retired, Parker and his wife moved to
Arkansas where they took up the repair and restoration of a 100-year old family
home called the Thompson House, which is on the National Register of Historic
Places.”
His long term colleague Dick Scalan said, “The
house was a complete wreck. It was leaning in two directions and the chimney
was falling down,” he said. Over a period of three or four years, Parker used
jacks to level it, he replaced parts of the frame and dismantled the rock
chimney (numbering all the pieces) and put it back together.”
Parker's old house in Arkansas |
Parker’s son Dan said, “He was a fun, cheerful and
highly likable man who moved through life with a positive attitude, despite
having a congenital condition that caused his bones to be highly brittle for
many years. On and off, from the time he was a child to just this year, he
suffered literally dozens of broken bones all over his body from simple falls.
He spent many months in casts over the course of his lifetime. And yet, he
maintained good humor and an optimistic, constructive outlook on life.”
I served on the Treibs Medal Nomination Committee
that recommended Parker for the prestigious Treibs Medal given for lifetime
contributions to Organic Geochemistry. Parker couldn’t come that year because
of a broken leg, but made it to the following GSA meeting in Denver. I recall
sitting near the front of the audience listening to Dick Scalan give the
citation. He showed a picture of Parker in an old, ragged white T-shirt, fixing
up his house in Arkansas.
Parker looked just like a
hillbilly, which indeed he was in some ways. I watched the facial expressions
of some of my more distinguished colleagues, who seemed to squirm slightly in
their seats.
He’d made it to the top of
his field with international acclaim all on the back of his creative spark as a
young scientist and his talent at picking bright students. When Parker took the
stage to accept the medal, he was humble—the way he’d always been.

Marilyn, I think you captured my dad's character and spirit well. Thanks for writing this. - Dan Parker
ReplyDeleteMarilyn,
ReplyDeleteThank you so much for filling in some of my academic history. And I loved your piece on Engel and Macko. I have always appreciated my link to Pat Parker although we never met. Pat passed away shortly after I received a RAPID grant to evaluate the impact of the Deepwater Horizon oil spill on O2 metabolism in the Gulf. It turns out there isn't much of a link although we published two papers addressing sediment vs. water column respiration based on stable isotopes. In writing, I recalled the other great Gulf oil spill, Ixtoc, and Pat's research on the tarballs washing up on the beaches (my brother pointed out that Ixtoc can be respelled as Toxic!). In any event, I dedicated the paper to Pat's memory (GCA 140: 39-39 (2014). Best wishes and keep writing,
Nathaniel Ostrom
