Happy Birthday, Gary! The first time I met Prof. Gary Hieftje was in Orlando, FL, 30 years ago, when I attended the 1982 Winter Conference on Plasma Spectrochemistry, organized by Ramon Barnes. Gary's talk was so interesting that I decided to visit his laboratory after the Winter Conference. However, a big snow storm prevented me from flying there. After that, I never had another chance to visit there. Since then, thanks to the “Open Policy” of China after the “Cultural Revolution”, we met from time to time in various occasions in various countries, including China and the United States. Gary was frequently invited to attend national and international conferences and symposia held in China. For instance, we invited him to give a plenary lecture at the Xiamen International Symposium on Spectrochemistry in 1996 (Fig. 1), and he was invited to the biennial Beijing Conference and Exhibition on Instrumental Analysis (BCEIA) as plenary or keynote speaker several times. In 2007, the Colloquium Spectroscopicum International XXXV was held in Xiamen, China. In that occasion by the unanimous decision of the Continuation Committee, he was the recipient of the CSI Award (Fig. 2). Mrs. Hieftje (Susan) was, as always, an active and enthusiastic companion. Gary hosted at least 20 students, postdocs, and visiting scientists from China in his lab, and has been always very kind, considerate, and helpful to them. On the other hand, most of these Chinese young researchers are outstanding. For instance, Qinhan Jin (QJ) visited Bloomington and collaborated with Gary to improve his Microwave Plasma Torch (MPT); Mao Huang was involved in the application of the computer-aided laser Thomson and Rayleigh scattering technique for measuring spatial distribution of physical parameters, e.g., electron temperature, gas temperature, and electron number density, in plasmas

(ICP, MIP, and GD); and Keling Liu investigated 2D spectral shifts of an echelle cross-dispersion spectrometer as functions of wavelength, ambient temperature and humidity. Finally, Pengyuan Yang spent also some time as a postdoctoral fellow in Gary's lab…. Some of them had follow-up visits to Bloomington (Fig. 3). Our spectrochemical laboratories at Xiamen University benefitted considerably from Gary's work. For instance, in late 1980s, we investigated a microsecond pulsed power supply for the conventional hollow

cathode lamps (HCL), and found that it enhanced the HCL emission of both atomic and ionic lines, with much greater enhancement for the ionic lines, as compared with the same HCL powered by DC or conventional millisecond pulses of equal average currents. As a logic follow-up, we wanted to apply a similar technique to the glow discharge (GD) ion source for mass spectrometry. Because of the pulsed nature of the microsecond pulsed GD source, TOFMS was the natural choice to exploit the advantages of the source. At that time, few studies were available in the literature about coupling a plasma with TOFMS. Pengyuan Yang and Wei Hang spent a considerable amount of time to figure out the details of the pioneering work on ICP-TOFMS described in several of Gary's papers. Pengyuan Yang even visited Bloomington to learn the interface and data acquisition techniques. A year later, we succeeded in operating our GD-TOFMS. The microsecond GD proved to be a powerful analytical source with some unique applications, in addition of being a versatile plasma diagnostic tool. Again, much of the work performed was inspired by a “short” paper with few experimental results (D.P. Myers and G.M. Hieftje, “Preliminary Design Considerations and Characteristics of an Inductively Coupled Plasma-Time-of-Flight Mass Spectrometer”. Microchem. J., 48 (1993)259–277).

“Art is long, and time is fleeting.” In 1986, Dr. Howard Malmstadt introduced himself to me with a big grin: “they call me Grandfather.” Now that Gary's 70th birthday is coming, I think Gary might also say with a big grin: “They call me Grand Father, too.” Dear Gary, we, all your friends and students in Xiamen, want to greet you sincerely: Happy Birthday, Gary!
