Farewell Sir Charles
by: James Trolinger


Dr. Chuck Vest (1941-2013)

Our dear friend and Holoknight, Charles of Washington, (Dr. Chuck Vest) passed away on December 12, 2013. The world and science community has suffered a great loss and will miss him dearly. The high standard, purpose, and mission of the International Order of Holoknights could not have been represented any better than by Chuck’s friendly, strong, and effective history and presence as an outstanding member of our order. We are all extremely proud to have him as a fellow Holoknight, and we will never forget him. The life and career of Chuck Vest is proof that a really nice person can achieve huge goals.


An excellent summary of his amazing career was presented in the MIT Newsletter,

A memorial service will be held at 1:00 pm on January 25th, 2014 at the First Presbyterian Church, located at 1432 Washtenaw Avenue, in Ann Arbor, Michigan. A reception will follow in the Pendleton Room of the Michigan Union along with a short program of remembrance from University of Michigan colleagues. On February 20, 2014 the Charles M. Vest Life Celebration at the National Academy of Sciences in Washington, D.C. will be held, and, on March 6, a memorial will be held at MIT.


I have known Chuck for nearly 50 years. After having received our advanced degrees in the same years, 1963, 64, 67, I used his Ph.D. thesis work in my first researches in holography a year later. Among the many contributions he made to the field of holography, his book, Holographic Interferometry, was a godsend for many holographers and teachers of holography, who were still struggling to find simple understandable ways of presenting this relatively new field. Even after his career diverted him from holography into high positions such as Provost of the University of Michigan, President of M.I.T. and finally President of the National Academy of Engineering, he never lost his interest in holography, showing up at our meetings, and welcoming us for casual visits. 


Chuck was knighted, Charles of Washington, in Springfield Massachusetts, in October, 2008 and presented with the sword of Charlemagne (Charles the Great).

Nine Holoknights were present for the ceremony, which took place at a technical meeting on holographic interferometry, hosted by Rich of Massachusetts. After the ceremony, the restaurant provided Chuck a special tribute, a belly dancer, with whom he was quite pleased.

Special Entertainment for the Newest Holoknight

As always, the newest Holoknight is charged with selection of the next Holoknight after conferring with and hearing suggestions from the other Holoknights. The selection process spans an extended time in email discussions between the Holoknights, and can sometimes get a bit testy (This one was no exception.) Nevertheless, the final choice is up to the newest Holoknight, and Chuck listened and responded politely to all of the comments before making his choice. He knighted Nadya of Saint Petersburg, who became our second female Holoknight. This was especially fitting since Chuck had become known as an advocate for equal treatment of the genders.

James Wyant is Knighted


Professor James Wyant, of Tucson, Arizona was knighted “James of Arizona” by Lady Cristina of Vigo, the current reigning Holoknight, on September 09, 2013, during the Fringe 2013 conference banquet. The venue was at the amazing "Musikhalle" in Ludwigsburg, Germany. Earlier, all conference attendees had visited the Ludwigsburg Residential Palace.

During the ceremony Lady Cristina read the parchment and knighted Professor James Wyant to become James of Arizona. After becoming a holoknight he was be given the special sword chosen by her along with the parchment, which is signed by the other holoknights who were present . 

Before the Ceremony

Part of the process of accepting knighthood is to accept the charge to choose the next holoknight and a venue for the ceremony, usually an international optical meeting or workshop. The Fringe 13 meeting was agreed. Holoknights discuss candidates among themselves and offer advice; however, the ultimate decision is that of the newest holoknight, with the guideline that the new member should reside in a different country from his/her own. Cristina of Vigo, the newest holoknight, conferred with all of the other holoknights, considered suggestions, examined candidates, and made the final choice. Only holoknights know who the new one will be until it is announced at the beginning of the ceremony. Holoknights must ensure that the new holoknight will attend, without disclosing the secret. The most recent knight makes the final decision, produces the scroll, acquires a sword and brings it to the meeting. 
































Holoknights gather before the service to sign the parchment, also providing an opportunity to see and hold the selected sword.

After the knighting ceremony the Holoknights gathered to congratulate their new member and for a group photo. Werner of Bremen, the grand master, announced that a new symbol had been adopted for holoknights to complement the sword - a small silver holoknight pin that can be worn on a coat lapel. He made a few presentations of the pin. 

Holoknights promise friendship and support for all holoknights in matters both personal and professional.

Pierre of Ghent Passes Away


A Great Master of Holography Pierre of Gent passed away on October 27, 2010. Pierre will be remembered through his innovations in holographic interferometry, pulse laser holography, holographic 3D displays and portraits, and simply as a very dear friend. Pierre was a professor and department head of the University of Ghent where for many years he operated a world class holography laboratory and studio. He was a pioneer in the development and application of pulse holography techniques to a wide range of non destructive test applications. He also supported the holographic art community by availing his advice and laboratory to artists. His unique bleaching formulas were widely used in the art community. Pierre, himself, created and exhibited many excellent fine art works. He developed an art studio and made hundreds of holographic portraits including a portrait of King Leopold of Belgium. Pierre's portraits are some of the finest in existence and have become extremely valuable collector items. 


Pierre was awarded the medal of the order of Leopold II, a rarely given, by “royal decree” award for outstanding service to his country.


Pierre and his lovely wife, Brigitte, were legendary as hosts to many who visited Ghent. Pierre left no stone unturned to insure that guests see and experience the country that he loved, commonly giving personal tours of Ghent and Brugges and visits to his lovely country home. 

Pierre was knighted Pierre of Ghent in September, 2001 by reigning holoknight, Wolfgang of Berlin. The knighting service took place in Bremen Germany at a “Fringe” conference. 


He is survived by his wife, Brigitte, two sons, two daughters, and seven grand children.

Dr. Hans Rottenkolber, Founder of the International Order of Holoknights, 
Joins God's Holography Team 

March 7, 2008

Hans Rottenkolber began his new assignment with God on 7 March, 2008. He was a great human being and scientist, having made important contributions to the field of holography. His company pioneered commercial holographic interferometry and was first to offer a practical system that employed thermoplastic recording material. We all loved, respected, and honored this man, whose very presence would bring warmth to a gathering. 

He founded the order of Holoknights over 20 years ago to honor those who were not only important contributors to the field of holography but who also were great promoters of international friendship and cooperation. He will be missed greatly by the community.

Chuck Vest Elevated to Holoknighthood

October 27, 2008


In a knighting ceremony held in Springfield, Massachusetts Dr. Charles Vest, President of the National Academy of Engineering and President Emeritus of the Massachusetts Institute of Technology, was elevated to the level of Holoknighthood by Sir Vladimir of Kiev (Dr. Vladimir Markov), the last knighted member of the International Order of Holoknights. The brotherhood, founded by Dr. Hans Rottenkolber in 1988, to bring together as friends the top researchers in the field of holography, celebrates its twentieth anniversary this year. The charter of the order promotes cooperation, hospitality, and friendship among holoknights and their countries. Members are selected not only for their technical leadership but also for their reputation for hospitality, openness, and assistance to others. 

The ceremony took place during the Society for Experimental Mechanics International Symposium to Commemorate the 60th Anniversary of Holography which was organized by Holoknight Professor Ryzard Preputniewicz (Rich of Massachusetts). Dr. Vest was a keynote speaker in the conference; however, he was unaware of his selection until the final moment since this information remains a secret unknown outside the order before the knighting takes place. 


Sir Vladimir of Kiev knights Chuck Vest. He was presented the sword of Charlemagne, which was used in the ritual, and a parchment proclaiming his new title, Sir Charles of Washington.





The sword of Charlemagne, used in the knighting service and presented by Vladimir of Kiev to Sir Charles of Washington, is engraved, “Sir Charles of Washington, Holoknight. The parchment was signed by nine other holoknights who attended the service.

Dr. Charles M. Vest is President of the National Academy of Engineering and President Emeritus of the Massachusetts Institute of Technology. 

At the University of Michigan he served as associate dean of engineering from 1981-86, dean of engineering from 1986-1989, when he became provost and vice president for academic affairs. In 1990 he became president of the Massachusetts Institute of Technology (MIT) and served in that position until December 2004. He then became professor and president emeritus. 

In July 2007 he was elected to serve as president of the U.S. National Academy of Engineering (NAE) for six years. He has authored a book on holographic interferometry, and two books on higher education. He has received honorary doctoral degrees from ten universities, and was awarded the 2006 National Medal of Technology by President Bush. 

Held at the peak of the autumn colors in Massachusetts, attendees were treated to an explosion of color surrounding Springfield.

2006-Markov becomes the newest Holoknight

September 14, 2006

Dr. Vladimir Markov became the latest to be knighted into the International Order of Holoknights. The special knighting service was held at the banquet of the International Conference on Speckle in Nimes, France on Thursday, 14 September, 2006. Organized and headed by Dr. Pierre Slangen, a professor at the School of Mines, Ales, France, the conference was attended by top scientists in the field from around the world and convened from 13-15 September. 


In keeping with the selection rules, Markov was selected from the top holographers in the world by Rajpal of Bhopal (Professor Rajpal Sirohi of Bhopal, India,) who was the holoknight inducted by the order in 2005, and was confirmed unanimously by the full council of holoknights. He was presented with a Holoknight sword and a parchment signed by attending holoknights. His new title is Vladimir of Kiev. The knighting portion of the service was conducted by Wolfgang of Berlin (Professor Wolfgang Osten), who heads the Institut für Technische Optik, Universität Stuttgart, Germany. Rajpal of Bhopal, who would normally perform this part of the service, was unable to attend. 

Other holoknights in attendance were Werner (Juptner) of Bremen, Malgorzata (Kujuwinska) of Warsaw, Paul (Smigielski) of Alsace, Pierre (Boone) of Gent, Armando (Albertazzi) of Catarina, Mitsuo (Takeda) of Tokyo, and Rich (Preputnievich) of Massachusetts.

Wolfgang of Berlin knights Vladimir of Kiev-The parchment and sword, held by Wolfgang, were then given to Vladimir, the latest holoknight. 


Dr. Markov Pioneered the study of the basic properties of volume holograms recorded with random amplitude-phase (speckle) encoded reference beam which leads to ultra high-density data storage in volume hologram recording with speckle-shift selectivity. Dr. Markov also did extensive study and performed the first experiments with two- and four-beam coupling in a resonant medium (sodium vapor). He demonstrated the possibility of extremely high gain for signal beam amplification. He was first to propose the possibility of applying the optical double-transform Fourier

In 1994, Markov established and became the first Director of the Institute of Applied Optics of the National Academy of Sciences of Ukraine. In 1995 he became the director of the Institute of Optics of Bogota (Columbia). In 1998 he joined MetroLaser Incorporated, Irvine, CA and is currently a vice president and the head of the Applied Optics Group. He was a close friend and associate of Professor Yury Denisyuk, one of the fathers of holography, who passed away in June, 2006. He gave a memorial talk on Denisyuk at the Speckle 06 conference.
