Theodore Kuwana

 

Theodore Kuwana, a son of Japanese immigrant (Issei) parents Yoshino and Nenokichi Kuwana, was born August 3, 1931, in Idaho Falls, Idaho, in the United States.^[1][2]

Kuwana wrote, "I was the youngest of six children; my parents were immigrant tenant potato farmers... When I was 10 and 12, I lost my father and mother, respectively, to cancer. Early on, mother had said, 'You must go to college.' I was the only one in our family to do so."^[3] His interest in chemistry started while he was in elementary school, when he was given a Gilbert chemistry set one Christmas. In high school he won the Bausch & Lomb Medal for Excellence in chemistry.^[3]

Kuwana's baccalaureate degree in 1954 was from Antioch College where with R.G. Yalman he published his first research article in a major journal.^[4] His M.S. in 1956 was from Cornell University.^[2] Kuwana earned his Ph.D. in 1959 at the University of Kansas, with a dissertation titled, Studies in Electroanalytical Chemistry: The Development of a Mercury Chloride Film Anode and Chronopotentiometric Studies in Aqueous and Non-aqueous Solutions, supervised by Ralph N. Adams.^[5]

In 1965, Kuwana wed Jane Bader.^[6] Because she understood the chemistry and was also a talented writer and editor, she edited his writings. The couple had a son, a daughter, and four granddaughters.^[2]

After postdoctoral training with Fred Anson at California Institute of Technology, Kuwana briefly worked at an aerospace firm^[3] before he went to the University of California, Riverside, in 1960 as a visiting assistant professor.^[7] He became an associate professor at Case Institute of Technology (now Case Western Reserve University) in 1965, and a full professor there in 1968. From 1971–1986 he was on the faculty of Ohio State University. Kuwana joined the faculty at the University of Kansas in 1986, becoming Regents Distinguished Professor of Chemistry and Pharmaceutical Chemistry, and the Director of the Center for Bioanalytical Research.^[8]

Kuwana is recognized as the founding father of spectroelectrochemistry:^[8][9][10]

The origin of spectroelectrochemistry at an OTE [optically transparent electrode] appears to date from a conversation held at the University of Kansas in the late 1950's between young assistant professor Ralph Adams and his first graduate student Ted Kuwana. As recalled by Kuwana, Adams, while observing the production of an intense yellow color in the solution near a platinum anode during the oxidation of o-tolidine commented that "...it would be nice to have a 'see through' electrode to spectrally identify the colored species being formed..." Later, Kuwana obtained samples of a conducting glass (antimony doped tin oxide-coated glass), and the first spectroelectrochemistry at an OTE was performed on o-tolidine.

Now equipped with a "see through" electrode, Kuwana and his students used these conducting glass OTEs for the first spectroelectrochemical experiments of electrogenerated solution species. Graduate student Keith Darlington and undergraduate student Don Leedy performed the experiments using o-tolidine, a colorless compound that undergoes a 2-electron oxidation to form an intensely yellow colored species – the very reaction that Kuwana studied as a graduate student at Kansas that sparked Adams' prophetic comment. They monitored formation of the yellow species at 437 nm using a constant anodic current (i. e., chronopotentiometry – a technique that was more commonly used at the time than it is now) and reported the results in their classic 1964 paper.

Describing Kuwana's "profound impact on analytical chemistry education", Wenzel, et al., wrote that Kuwana set up a series of workshops with industrial leaders to evaluate the undergraduate analytical sciences curriculum and design improvements. The main recommendation from the workshop participants was that "the undergraduate analytical sciences curriculum needed to engage students in problem-based experiences in the classroom and laboratory portion of courses."^[13]

The workshop participants also recommended a digital library of resources and links to resources for instructors designing problem-based learning for lectures and laboratories. Kuwana partnered with the American Chemical Society, Division of Analytical Chemistry, to set up a partnership for educational outreach. The Analytical Sciences Digital Library (ASDL) was formed, and it was supported with funding from the National Science Foundation.^[13] Kuwana served as managing director. Editor Cynthia Larive acknowledged "the leadership and continued contributions of Professor Emeritus Ted Kuwana, University of Kansas, to the development and continued evolution of the ASDL project".^[14]

 

According to Richard L. McCreery, "Ted Kuwana was not only a scientific leader in electrochemistry and related fields, but he was also an excellent citizen and unselfish contributor to the careers of many other scientists, myself included."^[15] Over his career, Kuwana advised and mentored 73 graduate students.^[16]

Kuwana died of pneumonia in Seattle on January 1, 2022, at age 90 years.^[2]
