Award to honor the memory of David Rognlie

David (Dave) Rognlie was a dedicated and much loved member of the crystallographic community, interacting over many years with a large number of scientists through his activities as owner of Blake Industries which sold diffractometer equipment including Huber equipment. In 2014 he sadly passed away and funds have been donated to establish a triennial ACA award in his memory.


The award is intended to embody Dave's values and personality: His generosity of spirit, optimism, selflessness and unstinting desire to help others to succeed in their endeavors.  Dave played a particular role in the x-ray synchrotron community, but had broad and wide-ranging interests in the science and the people doing it across all spectra.  The award will be for any meritorious discovery or advance in structural science by someone at any stage of their career. However, it is not intended to be a "lifetime achievement award" but for a particular discovery or development.


The award will recognize an exceptional discovery or technical development of particularly high impact in any area of structural science, to be awarded at any stage of a scientist's career without prejudice based on age, gender, ethnicity or race.


 Awarded every third year. The winner will receive an honorarium of $3000 and up to $1500 expenses to attend the ACA meeting to present a lecture covering the discovery or development that led the their selection.


The selection committee is made up of Simon Billinge (Chair), Bobby Barnett and Denny Mills.


The first Award was made in 2017 at the ACA meeting in New Orleans, LA.

Margaret C. Etter Early Career Award

  To recognize outstanding achievement and exceptional potential in crystallographic research demonstrated by a scientist at an early stage of their independent career. The award is established to honor the memory of Professor Margaret C. Etter (1943-1992), who was a major contributor to the field of organic solid-state chemistry. Her work particularly emphasized the use of hydrogen bonds and co-crystals. In addition to a large body of experimental work she was the major force in devising a set of rules known as graph sets to describe hydrogen bonds in a way that revealed similarities between structures without being tied up in the crystallographic details. Her experience teaching at an undergraduate institution and in working in both an industrial and academic setting gave her an unusually broad perspective from which to mentor students and to support and encourage colleagues. She had a love for people, for science, and especially for people who do science, that we honor. Established in 2002 as an annual award, it consists of a monetary award of $1,000 and plaque. The winner will present a lecture at the American Crystallographic Association Annual Meeting.


Scientists involved in crystallographic research in the broadest sense will be eligible for the award. At the time of the closing date for nominations, nominees must be no more than 12 years beyond the awarding of their Ph.D. degree, not including career breaks, and must have begun their first independent (not postdoctoral) position within the past 10 years. Nominees employed in tenure-track academic positions must not yet have received tenure. Nominations must include a nomination letter clearly indicating accomplishments since the nominee began an independent career and assessing future potential. Additional supporting letters and a c.v. for the nominee may be provided but are not requirements. Self-nominations are permitted. Nominees may be employed in academia (including service crystallography), in industry or in government laboratories.


Recipient of 2018 award:  Jason McLellan to be presented at 2018 Toronto Meeting

Margaret C. Etter Student Lecturer Award

  Each Scientific Interest Group (SIG) and the Canadian Division have the opportunity to invite one student to receive an award and to present a lecture in one of the sessions organized by that SIG. Selections are based upon submitted abstracts and are independent of whether the student presenter originally requested an oral or poster presentation. Award winners are determined by the elected officers of the SIGs. Students who accept the invitation will receive a monetary award of $250, which is independent of any requests for support via the ACA Travel Awards.

Charles E. Supper Instrumentation Award

To recognize scientists who have made exceptional contributions to crystallographic instrumentation. Charles Supper emigrated from Germany to the United States in 1925, bringing an ability to fabricate almost anything mechanical. While at M.I.T. during the late 1930s, he collaborated with Martin Buerger in the development of the precession camera. This instrument was to become the most significant single-crystal camera of the second half of the century. By 1941, he recognized the need for a company to manufacture and supply high quality, easy-to-use, reasonably-priced instruments for the X-ray crystallographer and he founded the Charles Supper Company. Mr. Supper's innovative designs and methods led to the commercial availability of the Buerger precession cameras, the Weissenberg camera, Debye-Scherrer powder cameras, goniometer heads, devices to fabricate crystal and protein models, film measuring instruments and other useful diffraction accessories. In the mid 1960s, the firm also became a major distributor for various crystallographic products created by others. The Supper Award is given periodically and consists of an honorarium to present a lecture at the annual meeting. The Charles Supper fund was established by his son, Lee, in appreciation to the community of X-ray diffraction scientists for their continued support throughout the years.

ACA Fellows       Annual deadline for submission of nominations is April 1.

The ACA Council has established a Fellows program. It serves to recognize a high level of excellence in scientific research, teaching, and professional duties, but also service, leadership, and personal engagement in the ACA and the broader world of crystallography and science. Our Fellows program celebrates the excellence of our own members from within the ACA, and promotes their recognition worldwide to constituencies outside of the ACA, such as their employers, other scientific societies, and the government. ACA Fellows will serve as scientific ambassadors to the broader scientific community and the general public to advance science education, research, knowledge, interaction, and collaboration. This program allows us to significantly recognize and honor a broader cross-section of the membership than was previously possible with other, more specific awards. We envision that eventually about 5% of the membership will be recognized as Fellows, and will announce new inductees and honor all ACA Fellows at the annual Awards Banquet.  Click here for a list of ACA Fellows.


The procedure for nominating and selecting Fellows is as follows: A nomination package must be completed by the nominator, who must be an ACA member. In a cover letter, a case should be made for how the proposed Fellow meets the above criteria. A brief CV must also be provided, as well as two letters from other ACA members supporting the nomination. Nominations will then be passed to all current Fellows, who will be asked to vote on the suitability of the candidates. Fellows will be appointed by the ACA Council if a majority of those Fellows voting are in favor.
