board of directors of the GttingenLaser Laboratory as well as amember of the Academy ofSciences of Gttingen and

Heidelberg.

Professor Stefan Hell is the one

who opened an entirely newdomain in physics, the optical

nanoscopy. His exceptional works

are spadework in the domain of

super-resolution optical microscopy

with broad applications in nano-

sciences and nano-technologies. Dr.Hell has a definite contribution in

breaking the resolution limit

imposed by the diffraction and

represented by the mathematical

formula discovered by Abbe in

1873. The exceptional discovery of

professor Hell has huge imply-

cations in this moment in life

sciences research. Certainly, this

will contribute to a successfully

understanding of the nanoscopic

scale phenomena studied in mate-

urmat o explozie de publicaii nreviste de cel mai mare prestigiui c au aprut noi tehnici deinvestigaie care au la bazaceast descoperire, evideniaz

n mod ct se poate de clarvaloarea ei.

La 23 decembrie 1962, la Arad s-anscut copilul Stefan Hell, care lapuin peste 30 de ani avea sdevin o celebritate incontestabiln lumea tiinei. i-a petrecutcopilria n comuna Sntana undea urmat cursurile colii generale,

ntre 1969 i 1977. S-a nscris laliceul Nikolaus Lenau dinTimioara n 1977, ale cruicursuri le-a urmat pn n martie1978. i-a manifestat interesulpentru tiinele exacte nc dincursul colii generale, fiind

puternic ncurajat de ctre prini.n aprilie 1978 a plecat n Ger-

mains of life sciences. The impor-

tance of this discovery is funda-

mental for medical research. The

fact that the invention of professor

Hell was followed by an explosion

of publications in journals of great

prestige and the apparition of

new investigation techniques

based on this discovery clearly

highlights its value.

In December 23, 1962 the childStefan Hell was born in Arad andin his early 30s he become an

incontestable celebrity in scienceworld. He spent his childhood inSantana village where he fol-

lowed middle school between1969 and 1977. In 1977 he went tohigh-school Nikolaus Lenau inTimisoara and he attended thehigh school until March 1978. He

proved high interest for exactsciences since middle school,

being encouraged by his parents.In April 1978 he moved with hisparents in Ludwigshafen, Ger-many, where he followed thehigh-school courses until 1981,when he graduated. During highschool he was remarked not justfor his knowledge in physics and

n liceu s-a impus, ajungnd ntop, nu doar prin cunotinele ndomeniile fizicii i matematicii,dar i n cele ale limbii germane,lingvistica i etimologia devenindun hobby al su, n ncercarea dea descoperi legturile ntre

cuvinte derivate din diferitelelimbi germanice i schimbrilefonetice.

n perioada 1981 - 1987 a urmatcursurile Facultii de Fizic laUniversitatea din Heidelberg. Laaceeai universitate a obinut titlul

de doctor n fizic, n anul 1990,cu calificativul maxim (summacum laude).

Activitatea tiinific a profe-sorului Hell a nceput devreme, nperioada facultii, i s-a mani-festat prin interesul fa derezoluia microscoapelor optice.Din pcate, nu a gsit un sprijin ncadrul universitii pentru acestdomeniu, care n acea period nuera privit ca unul de interes. Dupobinerea titlului de doctor, oare-cum dezamgit de dezinteresul

fa de acest domeniu, fiind lipsit

mathematics, but for knowledge

in German language, linguisticsand etymology being his hobbies.He managed to discover links

between derived words fromGermanic languages and phonetic

changes.

Between 1981-1987 he attendedthe courses of Physics Facultyfrom Heidelberg University. Here

in 1990 he obtained the doctoraltitle in Physics with Summa CumLaude.

The scientific activity of professor

Hell begun early in faculty and

was manifested by interest in the

domain of optical microscopyresolution. Unfortunately he

didn't find in University any

support for this domain, which at

that time was an uninteresting

domain. After he obtained his

doctoral title, disappointed by thelack of interest regarding this

domain and having no financial

resources, he spent a couple of

months in solitude probably to

find solutions and to crystallize

his ideas. In a short time being

financially supported by his

grandparents he described the

first 4Pi microscope, which was

patented by him in 1991. He

presented the experimental rea-

lization of his invention in 1994 in

an article published in Optics

Letters. 4Pi microscope is the first

great achievement of Stefan Hell;

because this microscope has a

resolution of the order of 100 nm,

this represents an improvement ofseveral times of that obtained in

confocal microscopy. The reso-

lution improvement was obtained

using two microscope objectives

placed in opposition, which

focused the light on the samearea. In this way, the samples

placed in the common area of the

focal plane can be illuminated

with coherent light from both

sides, and the reflected or

fluorescent light can be collected

in a greater quantity and

coherently.

Under these conditions the solid

angle used for illumination and

detection is closer to the ideal

case. It is remarkable the fact that

Dei acestea au fostdeosebit de valoroase, n Ger-mania nu a putut obine mai mult,la acea vreme. n baza ajutoruluidat de un prieten finlandez, aintrat n contact cu un profesordin Finlanda care, la acea vreme,lucra n domeniul microscopiei cufluorescen aplicat n cercetrimedicale. Astfel, a obinut un postde cercettor principal n cadrulgrupului de microscopie cu baleiaj

young researcher Stefan Hell were

obtained despite of great financial

difficulties. Although at that time

the German Research Council

initiated a program for new

microscopy techniques develop-

ments with applications in

biology, Stefan Hell could not

obtain any founds. He did not

meet the requirements because he

had no laboratory and no guidingprofessor. The only positive thing

at that time was that he obtained a

post-doctoral grant between 1991

and 1993 at European Molecular

Biology Laboratory from Hei-

delberg, where he could publishhis first results. Although these

results were very valuable, he

could not obtain more in Ger-

many. With the help of a Finland

friend he contacted a professor

from Finland who was working at

that time in the area of fluo-

rescence microscopy for medical

research applications. Here he got

the job of senior researcher in

laser scanning microscopy group

at the University of Turku, where

he worked between 1993 and 1996

unde a lucrat n perioada 1993 -1996, cu o ntrerupere n 1994,cnd s-a aflat la Londra, n Depar-tamentul de Inginerie al Univer-

sitii Oxford. n aceast perioad,Stefan Hell a fcut o descoperireteoretic excepional, constnddintr-un principiu n baza cruiarezoluia n microscopia optic atrecut bariera dat de limitareadatorat difraciei. Acesta a fost

momentul n care rezoluia optic,descris de relaia lui Abbe iconsiderat ca fiind de netrecut, afost depit de tnrul cercettornscut n Romnia. Aceastdescoperire teoretic se afl labaza unei realizri practice de

excepie, care aparine, de ase-menea, lui Stefan Hell. Este vorbade microscopia cu baleiaj laserbazat pe golirea prin emisiestimulat (STED - stimulatedemmision depletion). Prin intro-ducerea conceptului de golireprin emisie stimulat, StefanHell a iniiat un domeniu decercetare absolut nou nmicroscopie, n cadrul cruia s-aajuns la o rezoluie de ordinulnanometrilor.

Ca ntodeauna n cazul marilor

genii, Stefan Hell a exploatat unlucru aparent simplu, obinnd

with an interruption in 1994 when

he was in London in the

engineering department of the

University of Oxford. During that

time Stefan Hell did an

outstanding theoretical discovery

consisting of a principle that

makes possible the overcoming of

diffraction limit by the optical

resolution. In this way, the young

researcher born in Romaniapassed the optical resolution

described by Abbe and con-

sidered to be unbreakable. This

exceptional theoretical discovery

stands at the base of an

experimental achievement ofStefan Hell. It is the laser scanning

microscopy with Stimulated

Emission Depletion (STED). By

introducing the concept of

stimulated emission depletion

Stefan Hell initiated an entirely

new research domain in

microscopy, which led to a

resolution of order of nanometers.

As always happens in the case of

greatest minds, Stefan Hell

exploited an apparently simple

thing obtaining fluorescence

signal from an area dimension

much smaller than the diffraction

limit by illuminating the sample

with two laser beams. By his

invention Stefan Hell proposed an

optical microscope equipped with

a laser scanning system with two

beams, one for excitation neces-

sary for obtaining fluorescence

from an area of the sample (for

which resolution is limited by thespot size on the sample) and

another beam (sent in the same

area in the moment when the

molecules are in an excited state)

which is tuned on the fluorescent

emission wavelength. The secondbeam having a longer wavelength

that that of excitation is designed

to achieve a stimulated de-

excitation in a similar way with

stimulated laser emission. Before

focusing on the sample the beam

which attains the depletion passes

through an optical interference

device (phase plate) that realizes

an interference minimum in the

middle of the beam, modifying

the beam shape into a doughnut

shape. In this way, the intensity of

the depletion beam will be zero in

the middle. Thus, the already

excited area will be de-excited in

the exterior edge and the

spontaneous emission which

gives the fluorescence signal will

be emitted just from the central

part of the beam. By increasing

the intensity of the stimulating

depletion beam, the depleted zone

will increase and the central partof the beam (from which we

obtain fluorescence signal) will

decrease. Thus fluorescence signal

can be obtained from a small zone

of several nanometers, which is

well below the diffraction limit.The attempts of young Stefan Hellto publish in Nature or Science histheoretical results regarding theresolution improvement by usingstimulated emission depletionwere unsuccessful, probably be-

cause the importance of hisdiscovery was not understood.The work regarding thisexceptional discovery waspublished in Optics Express in1994. After this, with great regretfor loosing the priority of

Despite the importance of his

discovery he made in Finland,

researcher Hell faced some new

financial problems regarding the

research in Finland. Thus, he

searched help from institutes and

universities from Germany. This

time, Tom Jovin who was thedirector at Max Planck Institute

for Biophysical Chemistry from

Gottingen appointed him leader

of a young research group. In

Germany he managed to build his

super-resolution microscopeinvention between 1999 and 2000.

In 2002 he was appointed director

at Max Planck Institute for

Biophysical Chemistry, being the

leader in the Nano-bio-photonics

department.

At Max Planck Institute hecreated an exceptional researchgroup composed by physicists,chemists, biologists and engine-ers. Their many research results

Este de remarcat faptul c nprogramele celor mai importantemanifestri tiinifice la careparticip, profesorului Stefan Helli se rezerv locul cuvenit, iarprezentrile sale n plen sunturmrite cu cel mai mare interes.

Acum, cnd trim n plin er

se pune ntrebarea: cum ar putea

progresa cercetrile n aceste do-

menii fr a se vedea ce se n-

tmpl la acest nivel. Profesorului

Stefan Hell i revine marele meritn faptul c a oferit un instrument

Profesorul Hell face din microscopia

optic o surs extraordinar de cu-noatere prin diversitatea coplei-

n ncheiere se poate aprecia cdecernarea titlului de Doctor HonorisCausa profesorului Stefan Hell o

eminent personalitate a lumii tiin-ifice din zilele noastre, un exemplu

It is remarkable that in the mostimportant scientific events wherehe is present, professor StefanHell has his reserved place andhis plenary speeches are watchedwith the greatest attention.

Now when we live in the nanoworld (nano-sciences, nano-tech-nologies) we can ask: hawresearches in these domains canprogress without seeing what ishappening at that level? ProfessorStefan Hell has the great meritthat he offered an instrumentwhich opens new ways innanometric scale research.

In conclusion we can say thatawarding the title of DoctorHonoris Causa to professor Stefan
