My dearest Bobby,

For Shmulik, Uri, David, Daniel and me, you were our truest and best friend. I felt safe in the world knowing that you were there there.
In times of crisis you offered yourself in a humble and extraordinary way, wanting to find out how you could help us.

I love your sense of humor, your playfulness , the way you led our Pesach Seder.

I feel your loss deeply and I am lost without you.

Anat, Uri, Davidi, Daniel and their families

En nombre de nuestra familia, con todo nuestro cariño y gran respeto:
Con profunda tristeza y con el corazón nos unimos desde Berlín al inmenso dolor por la partida de Boby, un ser verdaderamente excepcional. Aunque tuve el privilegio de verlo solo en contadas ocasiones, su presencia siempre fue luminosa, cálida, generosa y humilde. Pero lo conocí también a través de los relatos llenos de cariño de su querida esposa Lili, de su cuñado y hermano de la vida Roby, y de toda una familia que para mí no es “como” familia, sino familia en lo más auténtico del término.
Boby dedicó su vida entera a salvar otras vidas. Entregó su tiempo, su conocimiento, su pasión, su corazón —en todos los sentidos— con una entrega admirable. En lo profesional, dejó un legado imborrable en el mundo de la cardiología. En lo humano, dejó una huella aún más profunda: la de un hombre que inspiraba, que guiaba, que amaba intensamente a su familia, que hacía reír, y que supo mantenerse humilde aun cuando el mundo lo reconocía como uno de los mas grandes.
Su historia me intereso siempre, desde sus primeros pasos en Buenos Aires hasta su extraordinario camino en Chicago. El haber compartido una cena con Lili y Boby en diciembre pasado, en Berlín, fue para nosotros un inmenso regalo, que ahora atesoramos con aún más emoción.
Nos sentimos cerca, muy cerca, de Lili, Gabriel, Daniella, de sus nietos que eran su orgullo, de Roby, de Gloria, Julie, de toda esta familia a la que tanto quiero desde siempre.
Su ausencia deja una herida profunda, pero su luz —como médico, como maestro, como esposo, como padre, como abuelo, como amigo— seguirá brillando en todos los que tanto lo querían, lo admiraron y aprendieron de él.
Con un abrazo sincero y con lágrimas,
Pauli y familia

Dear Roberto

The early death of our mother contributed to the fact that we did not grow up together and pursued very different lives.

There is a part of me that wishes we had shared more moments, more memories, and more of the everyday. Life took us down different paths, but it doesn’t change how I feel knowing you’re no longer here.

I will always hold onto the thought of what could have been, and I will cherish the moments we did have—even if they were few.

Rest in peace.

Thank you and farewell

LANG, Roberto, Z.L., falleció el 10-6-2025. – Partió un grande, que se dedico con todo su corazón al corazón. Lo pensábamos eterno e irrompible, siempre presente para cada quien necesitara su palabra, lo hacía con el alma y su saber. Esta pérdida enorme para quienes lo amamos se extiende a la humanidad, sus aportes como científico son incalculables. Bobby nos deja mucha presencia y se lleva nuestra inmensa gratitud. A Lili, Gabie, Daniella, a toda la familia Lang y a toda la familia Hajnal estamos con ustedes en este inmenso dolor. Los amamos Juan Braslavsky, Mónica Imen, Julie, Ingrid, Dan, Oli y Max.

Dear Dr. Lang,
It was one of the greatest honors of my life to meet you and learn from you during my time in the non-invasive cardiac imaging lab at the University of Chicago. This is a friendly, international, professional, Collaboratory, warm and unique team in my life! Your passion and pursuit of excellence in patient care, your dedication to research and teaching, and your graceful leadership continue to inspire me every day.
Thank you for your encouragement and support.
With the deepest respect and sympathy,

Gracias Roberto. Gracias por cuidarme, guiarme, apoyarme, empujarme y enseñarme a través de cada cosita que todos los días haces. Esas que para muchos pueden pasar desapercibidas pero que atraviesan y dejan mucho más que cualquier lección de ecocardiografía. Gracias por hacer de mi un tipo nuevo, diferente y espero, mejor. El orgullo de haber compartido tantas cosas con vos no me entra en el pecho. Espero que, de alguna manera, vos sientas lo mismo. Quizás por eso, solo para asegurarte, me mandaste a Argentina con otro paper en la mochila para que me entretenga. Me lo llevo junto con tu risa ronca, la ternura de tus consejos y tu puerta siempre abierta para todos los que vemos en vos, al jefe, amigo, padre y abuelo que siempre quisimos y querremos tener. Quizás así, te extrañe un poco menos.
Te quiero inmensamente.

I am deeply saddened by the passing of Roberto, a true legend in the field of echocardiography. His loss is profoundly felt by the entire echocardiography community worldwide. I was fortunate to have known him for nearly 25 years. From 2003 to 2007, my family and I had the privilege of spending a month each summer in Chicago, thanks to his generous support. During this time, I worked on clinical studies and performed echo analysis using innovative equipment at the University of Chicago. Every morning, Roberto would pick me up for the hour-long drive from the northern part of Chicago to the university, during which we engaged in enriching conversations. His laughter and insightful discussions inspired me to become a better researcher. He mentored me, and through his guidance, I was able to explore the vast and fascinating field of echocardiography. I am grateful to have worked with him and his wonderful team for many years. He was not only my mentor but also my best friend. May God always bless Lili, Daniella, Gabriel, and other family members. Roberto, I look forward to seeing you again in heaven. Requiescat in pace.

Bobby met me on the day I was born (pictured). Being that my biological uncles lived out of town, he made So many special- from holidays where he always prepared something engaging for the kids, to any regular Sunday where he stood by the grill for ages so that there would be delicious food, he was always prepared…and all with his dry sense of humor, that would make anyone within earshot erupt with laughter. You will be so missed, Bobby.

Dr. Roberto Lang was a giant among men and his contribution to the human experience must be substantial. We feel certain that Dr. Lang touched many lives in a positive and lasting way.
A short story: An American, I lived for many years in Thailand. Our son was diagnosed with a “suspect” terrible genetic coronary disorder. As he was under the care of the top pediatric coronary specialist in the region, it was impossible to get a serious second opinion. Our son was exposed to many invasive tests during the next year – all inconclusive.
I opened up to my cousin, Andres Strauss in Argentina about our situation in Thailand. Andy told me he had a childhood friend who was a top echo specialist cardiologist. We forwarded all the images to Dr. Lang, who immediately reviewed them, and announced, “This kid has a healthy heart.”
The Thai specialist knew Dr. Lang, both by reputation and by being lucky enough to hear him speak at a training seminar.
Dr. Lang cared enough about people to break his regular routine of healing others and review our son’s case half a world away, only because his old friend Andy asked him. It might have been a small thing, but it made a big difference in our son’s life. I would guess that if he recognized our son’s need for his care, he must have done it 100,000 or more times., Dr. Roberto Lang’s legacy of caring for others is alive and will always be remembered in the brightest of light.

Dear Roberto,

We grieve your passing. You have championed so many of us to serve; to innovate; to problem-solve; to lead; to succeed; and to pay forward.
You have always helped us with your wise, timely, and sage advice. You have guided and mentored us with your passion, dedication to excellence, and have truly taught us the gold standard in our field. You have always inspired us with your collegiality, your humor, and your love for our profession – and beyond. We will dearly miss you.
I am truly honored to serve on your research staff. It is uniquely my badge of honor to have served as your Cardiac MRI physicist, and I cherish all the highlights in your Echo Lab.
From the bottom of my heart – which we once referred to as the apex with love –

Thank you, and Farewell.

We will dearly and most certainly miss you. I am truly honored to have served as your Cardiac MRI physicist. This is a unique badge of honor that I will cherish onward, and I will always remember serving as a member of your research staff.

From the bottom of my heart – or from the apex and with love – as once exchanged;

Thank you and farewell.

I know incredible stories about Roberto because Daniella his daughter always talked about him, and how proud she always is about him.
When my dad had a heart attack, Roberto took time of his own and without knowing me or my dad, analyzed the case, took time to call me once or twice and recommended me to doctors and gave me his professional opinion, and I couldn’t be more thankful for it. He went out of his way to help others without expecting something in return.

Being a technician under the esteemed Dr. Roberto Lang is something all of us hold dear to our hearts.
He was like a father to us, guiding and teaching, protecting and always fighting to be sure we were treated fairly. He gave us so much credit for our role in the field of echocardiology and although his absence will be felt so deeply, any of us who had the privilege to work with him will carry his words with us and continue to share his guidance as we pass the knowledge down to future technicians.

Roberto was a wonderful mentor and teacher. Without him, I would not have been able to stay in the US and build a life and family. This photo is from 2013 – all the Fellows. He was so kind and generous, a Master of his field, and will be so very sorely missed. My sincere condolences to his family. What a great legacy he leaves.

It is hard to imagine a world without Roberto.

He wasn’t just my mentor — he was my hero. He shaped my career, my life, and the way I see the world. I owe everything I have achieved professionally to him. But more than that, I owe him for the friendship, the unwavering support, and the belief he placed in me when I was still finding my way.

As a fellow, I looked up to him with awe. He had this rare combination of genius, warmth, and humility. He made you want to be better — not because he demanded it, but because you didn’t want to let him down.

Over the years, that mentor-student relationship became a cherished friendship. I cannot count the number of times I would pick up the phone just to hear his voice, ask for advice, share a laugh. And in return, he was always there — generous with his time, kind with his words, and full of that infectious energy that lit up every room.

His passing leaves a hole in my heart that words cannot fill. I will miss him terribly. But I will carry his lessons, his spirit, and his friendship with me for the rest of my life.

Thank you, Roberto — for everything. I hope you knew just how loved you were.

With deepest love and gratitude,
Akhil

I am very sorry for your loss! I very much respected and appreciated professional friendship with Roberto. I was a fellow in cardiology as Dr. Lang was a junior attending at the University of Chicago. We did first 100 transesophageal echocardiograms together. He was wonderful, dedicated teacher for many cardiology fellows like me. I always had fond memories of his vast knowledge, wisdom, wit, humor. I admired his hard work and enormous contribution to the field of echocardiography and cardiology. Through the years we had occasional contacts and always each meeting was very cordial and warm. He will be missed! With deepest sympathy,
Mirek
