Robert Curl

[2][3] Due to his father's missionary work, his family moved several times within southern and southwestern Texas, and the elder Curl was involved in starting the San Antonio Medical Center's Methodist Hospital.

[5] His research program included both experiment and theory, mainly focused on detection and analysis of free radicals using microwave spectroscopy and tunable lasers.

[9] In 1985, Curl was contacted by Harold Kroto, who wanted to use a laser beam apparatus built by Smalley to simulate and study the formation of carbon chains in red giant stars.

[9] Over the course of 11 days, the team studied and determined its structure and named it buckminsterfullerene after noting its similarity to the geodesic domes for which the architect Buckminster Fuller was known.

[10] This discovery was based solely on the single prominent peak on the mass spectrograph, implying a chemically inert substance that was geometrically closed with no dangling bonds.

Later experiments confirmed their proposed structure, and the team moved on to synthesize endohedral fullerenes that had a metal atom inside the hollow carbon shell.

[11][12][13][14][15] The fullerenes, a class of molecules of which buckminsterfullerene was the first member discovered, are now considered to have potential applications in nanomaterials and molecular scale electronics.

[19] Curl's later research interests involved physical chemistry, developing DNA genotyping and sequencing instrumentation, and creating photoacoustic sensors for trace gases using quantum cascade lasers.
