Index to Mathematical Games

This is an index of Martin Gardner's 297 monthly columns in Scientific American from 1957 thru 1981. Martin also wrote four (4) regular articles for SciAm, indexed here by author 'MGA', the first in 1952 and the last in 1998!

After Martin 'retired' to focus on writing more books, the column was carried on for two more decades by various others, whose columns are also indexed here.

This index was originally posted on the web with Martin's permission in 1999.

Summarized in Words

After two initial articles (Logic Machines and Hexaflexagons) in Scientific American, Martin wrote 288 consecutive monthly Mathematical Games columns.

Then DRH and MG alternated for one year.
Then DRH continued solo, running his count up to 25 articles.
Then MG supplied two columns (#295 and #296).
Then Brian Hayes did six columns.
Then Fred Gruenberger did a column!
Then AK Dewdney did 73 (interrupted by #297 from MG).
Then AKD and IAN alternated during ~1991, bringing AKD total to 78.
IAN went on to complete a total of 96 columns.

If you count {MAR52, DEC56, JAN67, JUN86}, Martin had 301 articles and columns in SciAm. If you count Mathematical Games only, that would be 297.


About the Index

This index was created and is maintained by John Miller, Portland, Oregon. Read about John's connection to Martin.

I started the index in the 1970's on 80-column punch cards. Late 70's, I migrated it from IBM 1130 system to VAX 11/780, and a homegrown database. Late 1980's, imported into a Macintosh spreadsheet.

While on Sabattical in 1988-89, I finished compiling the Subject lines of all the years of Martin Gardner's columns by visiting the Portland State University library to peruse months earlier than in my own collection. I also indexed subsequent incarnations, such as Metamagical Themas. Since I compiled the index for my personal use, I sometimes abbreviated titles, and a few short titles may remain (11/2014).

When WWW came along, I used Perl to generate an HTML table from CSV text file. Same way today, with data exported from Open Office.

On October 8th, 2014, certain fields were pirated over to Wikipedia (now out of date). On October 23rd, we moved the index here to martin-gardner.org for safe keeping. Eventually, G4G may put this site into a content management system.

Books based on MG

The MG columns have been repackaged variously into many books. Since the book chapter titles often differ from original MG column titles, we'd like to cross-reference MG columns with MG books. Here are two good book chapter indexes, and one assortment of references:
