Leonard Adleman is a noted theoretical computer scientist and professor of computer science and molecular biology at the University of Southern California.
He is known for being the inventor of the RSA (Rivest-Shamir-Adleman) cryptosystem in 1977, and of DNA computing.
For his contribution to the invention of the RSA cryptosystem, Adleman was a recipient along with Ron Rivest and Adi Shamir of the 2002 ACM Turing Award, often called the Nobel Prize of Computer Science.

 Wettestware - computing with DNA Discover - Find Articles
Adleman tackled a version of the "traveling salesman" problem, in which a person is presented with a map of a certain number of cities, a number of specified roads connecting the various cities, and a starting and an ending point.
Adleman mixed in a test tube some 100 trillion DNA molecules containing all 7 cities and 14 roads, and let them join up as they saw fit.
But because Adleman used so many copies of each DNA city and street, at least one of the combinations that formed was bound to link the cities correctly.

 Leonard Adleman - Wikipedia, the free encyclopedia
Leonard Max Adleman (born December 31, 1945) is a theoretical computer scientist and professor of computer science and molecular biology at the University of Southern California.
RSA is in widespread use in security applications, including digital signatures.
Born in California, Adleman grew up in San Francisco, and attended the University of California, Berkeley, where he received his BA in mathematics in 1968 and his Ph.D. in EECS in 1976.

Len Adleman', one of the co-inventors of the RSA algorithm, provided some technical guidance on the film in exchange for giving his wife a chance to meet lead actor Robert Redford.
Len Adleman' is one of the three mathematicians who invented the RSA (he's the "A") cryptosystem, currently the preeminent method of encrypting any form of data in the world.
Adleman served as a mathematical consultant on the film, and spent several days constructing the slides Janek displays at the college symposium on "unbreakable codes" (which took Adleman a considerable amount of time to create using primitive early-'90s computer graphics technology).

 USC Viterbi School of Engineering : Len Adleman Wins Turing Prize
Los Angeles: Leonard M. Adleman, Henry Salvatori Professor of Computer Science and Professor of Molecular Biology at the University of Southern California is a co-winner of the Association for Computing Machinery (ACM)'s 2002 A. Turing Prize, for his contributions to public key cryptography.
Adleman concluded that DNA formation operates like a computer, and in a seminal paper published Nov. 11, 1994 in Science, demonstrated that DNA could actually be used as a computing medium to solve a simple problem.
Adleman is also associated with the creation of one of the first computer viruses, demonstrated November 11, 1983 by Adleman's student, Frederick B. Cohen, as a class assignment.

 The My Hero Project - Leonard Adleman
Born on December 31, 1945, Leonard Adleman was to become a theoretical computer scientist who would eventually unlock one of the many secrets of DNA.
Adleman came up with an idea to use DNA as a sequence to create the path between the cities.
Adleman would give each city a random sequence of six nucleotides (A, T, C, and G, representing Adenine, Thymine, Cytosine, and Guanine) and then by running DNA through several elimination style tests, would produce the correct sequence of nucleotides and thus the correct path.

 The Science of Secrecy
It was developed by Len Adleman, Ron Rivest and Adi Shamir, three professors from the Massachusetts Institute of Technology (MIT) Laboratory for Computer Science in Boston.
The crucial breakthrough was made by Ron Rivest, but appreciating that the research was very much a joint effort, he was planning to call the cipher ARS, the initials of the three inventors in alphabetical order.
Adleman felt uncomfortable about his name being first, as it was Ron Rivest who had the crucial insight.

 Special: DNA unraveled
But in November 1994, Len Adleman at the University of Southern California unveiled a model for an unconventional computer that just might lead one day to a solution of the traveling salesman problem: a test-tube containing one-fiftieth of a teaspoon of water teeming with DNA.
Virtually no one was working on DNA computing when Adleman, known for his work on computer security and for coining the term "computer virus," published his results in Science in 1994.
Respondents to Adleman's article have also detailed complex difficulties in scaling up his procedures, possibly limiting DNA computing to simple problems, for which conventional computers are already sufficient (or superior, since DNA computers are too slow at serial processing to compete with PCs or mainframes).

Len Adleman, the USC professor who led the research, says that DNA is actually quite similar to binary code.
While the experiment convinced Adleman that DNA computers will never be able to rival their electronic counterparts for speed without an unforeseen scientific breakthrough, he does think that they have a future niche.

 Scientific American: When did the term 'computer virus' arise?   (Site not responding. Last check: 2007-10-24)
Adleman pointed out the similarity to a biological virus, which uses the resources of the cell it attacks to reproduce itself, and the term "computer virus" began its journey into everyday English.
In 1983 the term "virus" was first coined to describe self-replicating programs by Frederick Cohen and his colleague, Len Adleman.
The first reports of serious damage from a PC virus occurred in 1986; the infection was caused by the "Pakistani Brain" virus, which was written by two brothers, Basit and Amjad Farooq Alvi, of Lahore, Pakistan.

I clearly remember the sense of excitement I felt opening the manila envelope with the 200-odd page mathematical proof, excitement that was soon followed by puzzlement and perplexity at the complexity of the proof.
With the help of a cooperative math professor, I was able to grasp in broad outline the nature of Adleman's proof -- although I have to admit I had no real appreciation of the implications or usefulness of an algorithm based on such a proof.

 DNA Computing
DNA computing was grounded in reality at the end of 1994, when Len Adleman of USC announced that he had solved a small instance of a computationally intractable problem using a small vial of DNA.
To implement step 1 of the algorithm, Adleman created a 20-mer sequence of DNA for each city A through G. For each path i>j, an oligonucleotide was created that was the 3' 10-mer of i and 5' 10-mer of j (see figure 2).
Although Adleman's first application of the computer took only milliseconds to produce a solution, it took about a week to fish the solution molecules out from the rest of the possible path molecules that had formed.

 Get Ready to Grow Your Own Computer ..... ; REVIEW - Technology - RedOrbit
On the way to describing how a colourful scientist named Len Adleman opened the door to this new science, Amos provides lucid histories of mathematics, computing, the invention of the integrated circuit and discovery of DNA, all of which are improbably knockabout and entertaining.
One of his default themes is the elliptical nature of discovery: significantly, Adleman is a mathematician who became interested in biology through an attempt to combat HIV.
In the 21st Century, the sciences appear to be reconverging, which means that mavericks such as biochemist Kary Banks Mullis, the only Nobel laureate who confesses enthusiasm for LSD and claims to have been abducted by aliens (no connection there, obviously), may well multiply like the bacteria being grown for their experiments.

RSA is an abbreviation that combines the initial letters of the last names of its three founders, Ron Rivest (R), Adi Shamir (S) and Len Adleman (A).
The algorithm was first propounded by Rivest, Shamir and Adleman in 1977 at the Massachusetts Institute of Technology (MIT) in the United States.
It was patented in the United States by the MIT in 1983 under patent No. 4, 405, 829, but the patent expired on September 21, 2000.
