Jew of the Week: Moses Maimonides

Maimonides

Moshe ben Maimon (1138-1204), known in the Jewish world as the Rambam (his initials) and to the rest of the world as Moses Maimonides, was born in Cordoba, Spain, the son of a famed rabbi. In 1148, the Almohads conquered Cordoba and began persecuting the Jews. Maimonides’ family fled and remained on the move across Spain for 10 years before settling in Morocco. There, Maimonides studied at the University of al-Karaouine, focusing on the field of medicine. At the same time, he composed his famous commentary on the Mishnah – the central text of Jewish oral laws. Along with his two sons, he then traveled to the Holy Land, despite the danger of the ongoing Crusades. After visiting the holy sites and praying at the Temple Mount, he journeyed to Egypt and settled there, continuing his work and studies at the local yeshiva. During this time, he played a central role in saving a community of Jews taken captive by King Amalric I. In 1171, Maimonides was appointed president of the Egyptian Jewish community. When his brother’s merchant ship sank in the Indian Ocean, Maimonides lost all of his wealth and started working as a physician. Having studied both Greek and Arabic medicine, and being well-versed in folk healing and mysticism, Maimonides quickly became the top doctor in the world and was soon hired by the legendary Sultan Saladin. Even after Saladin’s death, Maimonides remained the royal family’s physician, and rejected offers by a handful of European kings. He wrote a number of healing manuals that were influential for many future generations (and still studied today). He also composed several religious and philosophical works, including the famous Guide for the Perplexed and Treatise on Logic. His Mishneh Torah remains one of the central compilations of Jewish law to this day. He also set forth Judaism’s 13 Principles of Faith. Scholars are puzzled at how he was able to accomplish so much: his typical day included a visit to the Sultan’s Palace before returning home to a long line of patients that lasted into the night. He would rarely take any breaks, and ended his day hungry and spent. Even on Shabbat he had little rest, dealing with life-or-death situations that trumped the sanctity of observing the Sabbath. Many believe that he passed away because of this difficult lifestyle. Maimonides writes that he wished he had more time to pray, study, and grow closer to God, but his obligation to care for the masses superseded all these. He passed away on December 12th (809 years tomorrow) to great sorrow, and true to his nature, had demanded the humblest of funerals. He remains highly respected in Spain and across the Middle East, the Arab world (as Abu Musa bin Maymun) and the medical community. Countless institutions continue to bear his name, and he is a central hero for modern Jews as a man who was both pious and worldly, bridging the gaps between Torah and science, Jewish wisdom and secular philosophy.

 

Words of the Week

Gems from Moses Maimonides:

“Do not consider it proof just because it is written in books, for a liar who will deceive with his tongue will not hesitate to do the same with his pen.”

“Give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime.”

“No disease that can be treated by diet should be treated with any other means.”

“One who wishes to attain human perfection must therefore first study Logic, next the various branches of Mathematics in their proper order, then Physics, and lastly Metaphysics.”

“One should see the world, and see himself as a scale with an equal balance of good and evil. When he does one good deed the scale is tipped to the good – he and the world is saved. When he does one evil deed the scale is tipped to the bad – he and the world is destroyed.”

Jew of the Week: Robert Adler

Robert Adler & the TV Remote

Robert Adler & the TV Remote

Robert Adler (1913-2007) was born in Vienna where he received a Ph.D in physics. At the start of World War II, Adler fled to Belgium, then England, and finally to the US. He soon found a job working at Zenith Electronics, developing military technologies to support the war effort. After the war, Adler turned his attention to television. His first major breakthrough was the gated-beam tube, a revolutionary new type of vacuum tube that significantly reduced both TV costs and signal interference. Meanwhile, a fellow worker at Zenith, Eugene Polley, developed the first (wireless) TV remote control. However, this remote used flashes of light, and could therefore be triggered by sunlight. The company searched for a better solution, and one that required no batteries. Adler came up with a remote that used sound instead of light, and this became the standard for remote controls for the next 25 years (until replaced by infrared remotes that are common today – and unfortunately require batteries). Aside from the remote, Adler owned roughly 180 patents, including early forms of videodiscs and novel laser technologies. He filed his last patent (for improved touch-screen technology) at age 93! Working at Zenith for 41 years (and an additional 15 years as an adviser), he became the company’s vice-president and director of research. For his work, Adler received the coveted Edison Medal, as well as an Emmy Award.

The people of Israel did not believe in Moses because of the miracles he performed. So why did they believe in him? Because when we stood at Sinai, our own eyes saw and our own ears heard the fire, the sounds and the flames, and how Moses approached the cloud and God’s voice called to him…

Jews of the Week: Dov Moran, Dan Harkabi, and the USB Key

Dov Moran

The Universal Serial Bus (USB) key was invented in Israel by a tech company called M-Systems. The company was founded in 1989 by Dov Moran (b. 1955), a graduate of Haifa’s Technion Institute. Their first major project was creating an easy to use digital storage device that could hold a great deal of information in a small space. In 1995, M-Systems released DiskOnChip, the first ever flash drive. Building on this success, M-Systems patented the DiskOnKey in April 1999. The technology was quickly licensed by IBM and debuted in the US in late 2000, known as the USB Key. With 8 Mb of storage, it held over 5 times more data, wrote 10 times faster, and was far more durable (and smaller) than the standard floppy disk. The USB rapidly rose to popularity, and is now the most ubiquitous personal digital storage device.

Dan Harkabi

The project to develop the USB was led by Dan Harkabi, along with Amir Ban, Oron Ogdan, and company founder Dov Moran. In 2006, M-Systems was acquired by competitor SanDisk for $1.6 billion. Moran went on to start a company called Modu, which was acquired by Google in 2011. He now chairs two more Israeli tech companies, and recently launched a new start-up called Comigo, which is building systems to intertwine handheld devices with televisions. Meanwhile, Dan Harkabi – who served in the Israeli Air Force for over 20 years – is CEO of Picosmos, where he continues to work on flash drive technology.
