An extensive traveler, Rabbi Leib Tropper founded Kol Yaakov Torah Center in New York after learning from numerous Jewish scholars and authoring original interpretations of religious works. Rabbi Leib Tropper named Kol Yaakov in honor of Rabbi Yaakov Kamenetsky zt”l and opened the institution with the intention of educating those who sought to enter a conventional yeshiva environment.

Almost 10 years after establishing Kol Yaakov, Rabbi Leib Tropper created the group Horizons to promote a Torah lifestyle to unaffiliated individuals. In leading the organization, he has traveled to major cities in Europe, including Paris, Berlin, and London, as well as to many locations in the United States. At each stop, he lectures and teaches to share his knowledge of Judaism.

Rabbi Leib Tropper began his own religious education at a young age. He attended a Jewish elementary school and showed an early affinity for his faith. At age 12, he was studying the Torah at a 10th grade level. Two years later, he traveled to Israel to learn from Hagaon Rav Chaim P. Scheinberg, a Dean at Yeshivas Torah Ore. As a teenager, Rabbi Leib Tropper wrote original interpretations of challenging issues from the Tractate Kesubot and the Tractate Bava Basra. As a young adult, he returned to the United States to work at Ohr Somayach International, a school in New York. During his time at Ohr Somayach, he received instruction from several notable scholars, including talmid muvhak of the Chazon Ish zt”l Hagaon Harav Sroyohu Deblitzky shlita and Sephardic Chief Rabbi Rav Ovadia Yosef shlita.

Rabbi Leib Tropper has two grown children with families living in Israel and maintains strong ties with the country. He travels to Israel periodically to celebrate family milestones.


Stoicism and Serving god with passion - Rabbi Leib Tropper -Written by David Gold

Lecture delivered in Pennsylvania during the summer . Recorded  and written by 
David Gold
Marcus Aurelius praises his stoic tutor Sextus of Chaeronea for being free
From passion yet full of love AKA natural affection. (Meditations, 1.9)
Because the Stoics appear to have used the guidance of reason to pursue
Virtue it was easier for them to love the ordinary person. Reason offered them
A vision of some virtue in everyone. Emotion is often not fair and can be
Very discriminating.
The founder of Stoicism , Zeno of Citium which survived as a way of life for
Some for close to 500 years had a ’ way of of life ’ to offer. Modern day 
Philosophers are not certain how to understand and apply the principles of
Stoicism today. A passionless life of virtue is a complex idea.
The Torah perspective is quite different. The performance of acts of virtue 
Require passion , warmth or in Hungarian ‘patima’. 
In the book of Psalms King David says “all my bones speak your praises”.
When a Jew is able to serve consistently with enthusiasm, warmth and
Passion he/she have reached the capstone of spiritual achievement.
In some houses of service, silence during prayers is the way of the seriously
Penitent communicate.. And carries a palliative component for the common
We will soon see that the Jews in Egypt constantly raised their vocal
Protest to Hashem regarding their suffering. They CALLED out to G’D
Etc..far from a silent protest…
When Jews join in answering ‘yehay shamay raba’ in a gallant and vociferous
Manner , we are taught in the Talmud that the gates of heaven are opened
Even if they were closed.
The passion spreads to the physical as the body oscillates and the hands
Implore G’D for his intervention during what is called the silent shmone


Daas Torah: the words of the Chazon Ish,zt’l - Rav Leib Tropper-recorded by David Gold

A very confusing word to say the least. Daas Torah as a concept has been uncontested for the most part until relatively recently. Daas Torah which is the
Word used to express the view of the Torah in an authoritative sense, highlights
Those views that are not treated as if they are in the “domain״ of Torah  although
They ought to.

One is not considered to have “Daas Torah” unless they have earned the title
"Talmid Chochom". This statement would probably be contested,as it is quite
Difficult to achieve the status of a Talmid Chochom. In the maelstrom of our
Turbulent times there isn’t an abundance of people who are considered to be talmeidei chachomim.  It is our diluted perspective that allows us to believe
That one can be involved in prime rib ‘loshon  hora’ , learn Torah and be called a
Talmid Chochom. It is our “small mindedness” that allows us to merge a full time scientist and a part time learner who uses a computer search for Torah information,
To be categorized as a Torah Scholar.

That is by all standards an illusion. It is actually a dangerous illusion. Professional
Stand up comedians who learn for 3 hours per day are not Daas Torah though
They may act as if………

Sitting and studying everything but the depths of Talmud cannot qualify as a
Torah Scholar in the traditional sense of the word.

Rabbonim who tell tear jerking stories to their congregants may have the gift of
Articulation and power of inspiration . That has no influence on being a Torah
Scholar. (To be continued)

Rabbi Jacob Joseph School - Jewish Orthodox School in New York

With more than 40 years of experience as a rabbi, Leib Tropper has traveled worldwide to give lectures on the Torah. Prior to his career, Rabbi Leib Tropper studied at the Talmudical Yeshiva of Philadelphia and Rabbi Jacob Joseph School.

Established in Manhattan in the early 1900s, the Rabbi Jacob Joseph School focuses on academic achievement as well as spiritual development. The private elementary school relocated in 1976 to Staten Island and opened a separate girl’s division in 1987 to promote equal education among young ladies in a Torah-driven environment.

The school was named after Rabbi Jacob Joseph, a migrant from Lithuania. Before moving to New York, he was elected as communal preacher of Vilna, Poland. After arriving to the states in 1888, he was unofficially labeled the “Chief Rabbi” of New York. Using his leadership and religious status, he worked toward uniting the Orthodox community. Rabbi Jacob Joseph passed away in 1902. The following year, the school was named in his honor.

Teaching Children Punctuality

A scholar and teacher, Rabbi Leib Tropper offers practical guidance for living to organizations and individuals. A student of the Talmud, Leib Tropper mentors students through religious practices and close involvement with various youth organizations.

A main focus of youth organizations is to teach children the importance of punctuality. This starts by teaching them how to read both analog and digital clocks. Reading analog clocks provides them with the ability to visualize a time difference, while digital ones help to teach them math.

The next step is to explain to them that being late is not only an inconvenience to others, but that it may cause them to worry. In the event that children are tardy, they need to understand the importance of open communication. Finally, when children are on time, teachers or authority figures should celebrate with them. Positive reinforcement helps to build children’s self-confidence and fosters the development of healthy behaviors. Children who are taught how to be punctual have a valuable tool that will help them to succeed as adults.

Berlin’s Acclaimed Jewish Museum in Kreuzberg

New York-based Rabbi Leib Tropper founded Kol Yaakov Yeshiva and Torah Center in New York, where he is the rosh yeshiva. A keen international traveller, Rabbi Leib Tropper particularly enjoys traveling to London, Israel, Paris, and Berlin.

The internationally acclaimed Berlin Jewish Museum, in the Kreuzberg neighborhood, has attracted more than 7 million visitors since opening its doors on September 9. 2001. The striking building is the creation of Daniel Libeskind, an American architect with Polish Jewish heritage. The museum covers more than 3,000 square meters, with a permanent exhibition spanning German Jewish culture from the middle ages through to the present day. Temporary exhibitions complement the permanent one, covering numerous aspects of Jewish cultural history and contemporary Jewish German art. 

The Berlin Jewish Museum is best known for its striking architecture. Paneled in dark zinc, the structure contains, straight, winding, and fragmented sections, with plenty of empty spaces throughout the building. Libeskind chose this unique structure to represent tensions, both past and present, that appear within German Jewish social history.

Berlin’s Holocaust Memorial

New York-born Rabbi Leib Tropper is a prominent educator and the founder and rosh yeshiva of New York’s Kol Yaakov Yeshiva and Torah Center. An enthusiastic world traveler, Rabbi Leib Tropper enjoys visiting Israel, London, Paris, and Berlin.

The American architect Peter Eisenman is responsible for the controversial and deeply moving Holocaust Memorial near the Brandenburg Gate and Potsdamer Platz. Its official title is the Memorial to the Murdered Jews of Europe. Sprawled over approximately 200,000 square feet, Eisenman’s design was approved in 1999 and construction was completed in 2005.

More than 2,700 gray concrete slabs of various shapes and sizes have been used to create the memorial, all of which are unmarked. The ground beneath the slabs undulates, a concept that Peter Eisenman hoped would give the visitor a sense of instability and disorientation. Visitors are encouraged to walk in any direction at any time of day or night. An information center, adjacent to the memorial, is open from 10 a.m. until 8 p.m. daily.

The Life and Career of Rabbi Eliezer Gordon

Rabbi Leib Tropper is a highly respected educator and writer, closely involved with New York’s Jewish community. As a young student, Rabbi Leib Tropper attended the Rabbi Jacob Joseph School, Philadelphia’s Talmudical Yeshiva, and Ohio’s Telshe Yeshiva, where Rabbi Eliezer Gordon served as rav and rosh yeshiva in the late 1800s.

Lithuanian-born Rav Eliezer Gordon was the first rav and rosh yeshiva of Telshe Yeshiva, as well as a passionate Talmudist, Jewish educational innovator, and recognized Torah expert. He was also called Rav Leizer Telzer. Born in 1884, Rav Eliezer Gordon was lost as an infant in the snowy Lithuanian forests, where his family later discovered him being protected by a wolf. He began his studies at the Zaretza Yeshiva. Upon finishing there, he pursued additional studies at the Kovno Yeshiva, headed by Rav Yisroel Salanter, who later became a mentor and trained Rav Eliezer Gordon to assume rabbinical responsibilities.

After marrying Rav Avraham Yitzchok Noveizer’s daughter, Rav Eliezer became the rav of Kovno, but quickly moved on to Kelm, where he established a yeshiva. He subsequently accepted two further positions, one as the rav of Slabodka, and finally, as the rav of Telshe Yeshiva in America. Rav Eliezer remained in Telshe for the rest of his career. Among other things, he is remembered for establishing a remarkable kibbutz there.
