I remember when Antoni spend his first long-term - as a postdoc - stay in Jülich  because it was me who recommended him to you and you approved this with no seeing him even before.  
This was starting in fall 1989 (probably October) it lasted for three years. Then he was visiting Jülich regularly, usually two times a year, for as long as you were director.

Publications
Antoni published 43 papers with members of our institute or with visitors who he met in Jülich.
Many of the publication during this period were done in collaboration with N.N. (Kolya) Nicolaev (who was a member of our institute from ) and members of the Landau Institute: The Jülich-Cracow-Landau Collaboration

13. Kolya Nicolaev highlights some of Antoni`s research
Antoni joined ongoing efforts by Gerry Garvey and J. Speth to elucidate the impact of the nonperturbative meson cloud in nucleons on deep inelastic scattering of leptons on nucleons. With natural assumptions one is able to reproduce the NMC findings. Nucl. Phys. (1994)
The first ever summary of these ideas came out in 1994 as Physics Reports co-authored by B. Pearce, J. Speth and A. Szczurek, entitled: «Importance of the meson cloud to hadron structure» Phys. Rept. (1994)
The Jülich-Cracow-Landau Collaboration has extended the approach to the Drell-Yan lepton pair production, with successful description of the 1994 data by the NA51 collaboration and of the 1998 data by E665 Collaboration
The Collaboration proceeded to application of the meson cloud approach to predictions for the spectrum of leading protons in DIS and to the extraction of the pion structure function from DIS tagged with leading nucleons. These topics have been reviewed by Antoni in his article: «Leading nucleons from peripheral processes in lepton deep inelastic scattering and the nucleon structure», Progr. Part. Nucl. Phys. 43 (1999)

14. Kolya Nicolaev highlights some of Antoni`s research
Inspired by successful description of the flavor content of sea quarks in nucleons, the Jülich-Cracow-ITEP goup went after nonperturbative effects in the spin structure functions of nucleons. A comprehensive analysis of the flow of the polarization of nucleons into the orbital momentum of constituent pions and the polarization of constituent vector mesons has been published by: H. Holtmann, A. Szczurek and J. Speth, Nucl. Phys. (1996)
The interpretation of the EMC spin crisis remains as yet unresolved, but worth to mention is the diploma work by Wolfgang Schaefer (1997), then a graduate student at IKP, of the nonperturbative pion contribution to the tensor spin structure function of polarized nucleons. The experimental data on this structure function by HERMES Collaboration taken at HERA are fully consistent with Schaefer`s preductions.

15. Kolya Nicolaev highlights some of Antoni`s research
Antoni also joined a theoretical analysis of the onset of color transparency effects in quasielastic (e,e`p) scattering off nuclei. This 1994 study by the Jülich-Cracow-Landau-ITEP Collaboration remains a unique one in its consistent treatment of the coupled channel nature of the phenomenon with due allowance for the nonperturbative meson cloud effects and for QCD motivated description of final state interactions. Unlike many other authors who predicted large color transparency effects for protons at already several GeV`s, the Juelich-Cracow-Landau-ITEP Collaboration stated that one neeeds energies above several dozen GeV`s. The NE18 results from CEBAF fully confirmed this prediction.
It followed a Juelich-Cracow-Landau-ITEP analysis of nuclear broadening of the transverse momentum distribution of protons in (e,e`p) scattering by finals state interactions.
This study turned out to be the starting point for the PhD Thesis of Sabine Jeschonneck. Which brought her to MIT, then CEBAF and to a professorship at the Ohio State University.

16. From 2000 on Antoni was more busy with building a physics empire of his own in Cracow and elsewhere in Poland. He was much less frequently at, but still in close touch with, Juelich. The best proof of that is his former Juelich collaborator Wolfgang Schaefer who presently is a professor in Antoni`s department at Niewodniczański Institute of Nuclear Physics in Cracow.
I conclude with two pictures of Antoni at the Landau Institute for Theoretical Physics in June 2015, where Antoni was one of the key speakers at the Memorial Workshop «Exploring Quantum Field Theory», devoted to the 85th Birthday of Vladimir Naumovich Gribov.

Dear Antoni,
I conclude this Laudatio with wishes of many more fruitful years in physics. And our cordial wished to Magda - a strong support from family is imperative for productive work in science.

21. Happy Birthday
