Hirotugu Akaike was a renowned Japanese statistician best known for his significant contributions to statistical model selection and information theory. He was born on November 5, 1927, and passed away on August 4, 2009. Akaike's most famous contribution is the Akaike Information Criterion (AIC), which is a method for model selection that helps to estimate the quality of a statistical model relative to others.

Herman Wold (1908-2002) was a prominent Swedish economist and statistician, known for his significant contributions to econometrics, particularly in the areas of time series analysis and structural modeling. He is best known for developing techniques related to the estimation of structural models using instrumental variables and for his work in the realm of partial least squares (PLS) regression. Wold's research laid the groundwork for much of the modern approach to model specification, estimation, and validation in econometrics.

Herman Otto Hartley is likely a reference to the Hartley transformation or the Hartley function in mathematics and engineering, primarily related to signal processing and communications. However, if you meant to refer to an individual by that name, there doesn't appear to be widely recognized or notable figures by that exact name in available historical or contemporary records.

Henry Lewis Rietz (1854–1922) was an American mathematician known for his contributions to the field of mathematics, particularly in the area of numerical analysis and applied mathematics. He is recognized for his work on the Rietz problem and for advancing the understanding of numerical methods.
